No I'm not because karma doesn't affect your account on Lemmy as it would on Reddit. I can still say and do whatever I want with no restriction because my account isn't tied to karma. Like if I had been downvoted enough, posting would be a pain because of karma limits. But, I'm not weighed down by that so downvotes don't really affect me.
What it does tell me, is just there being a group of spiteful people, presumably from Reddit and maybe a of Lemmy's own. That just have too much time on their hands and again, are toxic people who refuse to see that they themselves are what's toxic but they love to put the blame on anyone else.
You can't simply comment everywhere. You need certain karma levels to post in select subreddits. That's why people spam so much in AskReddit is to build karma.
