It's just bots or spammers generating accounts on various instances (<- edited for clarity and correction) then using them to spam popular communities. Happens pretty regularly, but unfortunately if the home instance doesn't ban the user then each instance has to remove the spam themselves.
Also, there's no way to report a user to their home instance so long as they don't post anything in a community on their home instance. So the only people who can ban them in a way that federates to other servers also doesn't know unless someone sends them a personal message. And they are using a bunch of different instances to make it hard to do that.
Hello! My name is Akihisa Ito, aka ap12, and I am the operator of the criminal organization "Black Cat Server@ap12!! The criminal organization "Black Cat Server" to which I belong contributes to society every day! We operate VOICEVOX text-to-speech bot and VOICEROID text-to-speech bot, collect messages collected via bots and personal information of members, and sell them to hackers!
I suppose they're trying to sow fear or something? Like "your data isnt safe" which is bs.
Japanese Misskey/Mastodon servers have also been spammed by the exact same thing since about 15 hours ago, and it's still going. I guess they're targeting Lemmy as well now, damn...
masto admin here. my instances are also getting hammered from external traffic.
The annoying thing is, I don't think that masto has any good tools to check which instances are causing the traffic. Especially as it's getting rerouted through a relay in my case
I am seeing increase in pict-rs ram consumption although I'm basically alone in my instance. Any ideas what the reason could be? (edit: since around the same time I saw this stuff happening)

This us what the language setting is meant for. You'd think there'd be rudimentary language, checks at least at the character set level. Meanwhile, ι ψαν σςιτψη το Φρεεκ ςιτη νο προβλεμ.
You definitely do not want to set a post to Japanese just because they used a Japanese character. People's posts would not be seen by many people and they wouldn't know it was all because they were explaining a Japanese character to someone in English.
