So, after using Lemmy for 1.5 Years. You are telling I am not even allowed to use Lemmy?

I'm calling the police.

Why would you ever admit your age online?
- I'm not 23. Nobody likes you when you're 23.
- I'm 92.
  
  If 16 is too young for Lemmy, 92 is unfortunately too old.
  I'm sorry, but if you can't use it during the first 17 years of your life, you shouldn't be allowed to use it during the last 17 years either!!!!!!!11 Rules are rules...
  
  Hi 92, nice to meet you. How old ya

Imagine this, but with email.
- This meme could have been an email!

This particular thread is hosted on lemmy.world and you must be 18+ to access it.
Nah, admins only care about their own instance. So a LW admin would only care about underage LW users.
Admins don't have the time to moderate for other instances. I'm already busy enough with dbzer0, lemm.ee's business is theirs. (as long as they're not posting CSAM or scams)
edit: I should mention that you still have to follow the COCs of instances, but most of them can be boiled down to: Don't be a huge dick, and don't be racist/anything-phobic.
- And despite how simple it is people still find new and interesting ways to be bigoted. It’s impressive really
  
  As long as all those people getting banned were actually for those reasons...
  Most of the time admins and mods just ban you because they don't like you even though that's not a rule.
- lemm.ee allow 16+ year old users.
  
  Should be fine, then. You're on .ee not .world, they're not going to vet your account for age ;)

Not really sure how that works with federation. You're not "using" lemmy.world, you're using lemm.ee, which has a copy of content from lemmy.world.
- I think you've pretty much nailed it. KFC can't ban you from buying a Burguer King that McDonalds is secondhand selling.

Why is Kit on instance X gatekeeping a user in instance Y from accessing a community on instance Z?
Gives me vibes of old man yelling at kids to stop having fun.

Bans are for adults, you gets sent to your room.
- After you take out the trash.

No one under 18 years of age or under the regulated minimum age defined by your local law (whichever is higher), is allowed to use or access the website.

Curious choice
- Dealing with data protection laws surrounding children is a MASSIVE pain. Most Lemmy servers ignore the GDPR safely, but ignoring COPPA is a bit harder. And that doesn't even take into account the recent rise of laws blocking teenagers from social media, with varying ages and consent laws.
  
  "safely" as in are too small for the regulatory bodies to care. Takes one report though.
- It's legal boilerplate.
- There's probably some law that require it.

That doesn't make sense. Iirc, lemmy.world doesn't host any of your content or manages your account, it simply just displays it.
- This can get a bit complicated with federation. This community is hosted on LW. I am accessing it via sopuli.xyz, and you via feddit.uk. All (presumably) have full bidirectional federation with each other.
  When I hit send, this message will go to Sopuli's outbox, which will then sync to LW for this community. At that point, this post will live on LW's servers. Anyone accessing LW directly can see it, even if Sopuli were to go down. Later (probably less than a minute), LW will sync to Feddit.uk, at which point you will be able to see it.
  Note that this is for text posts only. There have been some changes around images and video, both for bandwidth and liability reasons.

I’m too old for this to matter, but is somebody really expected check the ToS of the server the community they’re posting in is on, or is this just a CYA kind of thing?
Federation makes this untenable.
- Yeah just ignore and move on. They probably just put that there so they dont get sued for making porn available to minors without warning or something.
- Yes, unless you accept the risk of being banned. Every community and every server has its own set of rules.
  You can usually safely ignore these rules, but if you get banned you don't have a leg to stand on if you didn't bother with reading the rules.
  
  Damn RIP then if I got banned from .world after this post I am leaving Lemmy.
- is somebody really expected check the ToS of the server the community they’re posting in is on,
  Technically yes. Practically nobody does.
- So, I am gonna check TOS of every instance wherever I am posting?
  
  You should understand the rules of the places you are posting to, yes.
  This is why "let's pretend this is centralized social media and ignore the fact that we're all on different websites" is a bad idea, actually. You don't get to parachute into someone else's house and expect the rules of your own home apply.
- No. All of your direct interactions are with your instance which federates with others.

is this like traveling to another country where the drinking age is lower
- No, it's like a 19 year old being on a conference call with Americans having a beer and Americans telling him he can't because in America the law is 21

I seem to be missing some context - anyone want to fill in the rest of the class?
Edit: the image being shown to ~~lemmy users~~ everybody else is not being shown to ~~mbin users~~ ~~me and/or fedia.io users (unclear)~~ some unknown subsection of mbin users including me, so here it is for those like me: https://imgur.com/q4zuZzz
- Must be your instance. I can see it fine from kbin.melroy.org, which also uses the mbin software.
  
  Well, now that's just discrimination :(
  Weird though!
  Edit: it also doesn't show for kbin.earth (which is running mbin) - I'm curious what the source of the problem is for this strange and seemingly-arbitrary minority of users https://kbin.earth/m/fediverse@lemmy.world/t/1028068/So-after-using-Lemmy-for-1-5-Years-You-are-telling

Kit comes across like a dickhead from that screenshot.
- An arrogant teenager?!?
  
  I don't know them to judge them. I can only judge the interaction and there's not even context for that. They could be a perfectly nice adult.

If an admin put limitations to who can or can't belong and/or interact with their server, it's their responsibility to whitelist and blacklist accordingly.

I cannot stress this strongly enough: You have not been "using Lemmy" for 1.5 years now. "Lemmy" isn't a service the same way Reddit is, it's a web engine, like Joomla, or like phpBB.
You've been using lemm.ee for 1.5 years.
Nobody wants to hear this, but there's no "Lemmy". This emergent network of social media sites isn't a coherent thing, and it's not a stable concept. The attempts to make this look like a singular space are to the ultimate detriment of the network, because implicitly lying to end users about what they're doing informs how they behave.
You've been using lemm.ee. Lemm.ee has copies of content on other websites, but those websites have different rules, and different expectations than lemm.ee. You don't get to pretend otherwise because of where you're reading the content, and there is no guarantee that you will have further access to content from any other website than lemm.ee.
This is a reality that people simply do not want to face, for some reason. Everyone wants to imagine that federation is just centralized social media with some voodoo in the background, but it is a fundamentally different paradigm, and this is the wild fucking west.
You're going to get your toes stepped on if you treat it like something it's not.
- Why would you type all this out? What a waste of your time yapping about nothing. It’s Lemmy, for better or worse
- The social media lemm.ee runs the software Lemmy and forms part, along side other social media (server/instances/providers) of the Lemmy network that simultaneously forms part of the Fediverse.
  OP and you too are on Lemmy because you are part of servers that run Lemmy, and that actively make part of the Lemmy network in all its aspects, up to its distinct userbase culture that differentiate it not only from the wider fediverse but also from other link aggregators like Mbin and PieFed.
  Not only is your comment painfully pedantic but also patently wrong.
- You realize the software most of us here use is literally called Lemmy, right?
  
  No, lemm.ee and Lemmy.world are using the Lemmy software. You are using a web browser or a mobile app which is decidedly not Lemmy
- That's some silliness right there.
  Using lemm.ee is using lemmy because lemm.ee is lemmy software being hosted on their hardware, and the activitypub that's part of lemmy connects everything.
  If you're going to try to be pedantic, be right
- When people say they are sending emails, do you also ask them which email provider they use to correct them?
  
  If you email someone on a different mail service and your message breaks the ToS of their mail service then you shouldn’t be surprised if your email address gets blacklisted.
  
  Different providers have different spamfilters, different rules regarding html mails, attachment file size, use of tls, policies regarding exspired certificates, and might have different log in procedures, so yes, if there are problems the question which providers are involved.
- they have been using the lemmy software.
- Let me check my email
