They aren’t in your face about the tankie stuff on lemmy.ml but when it comes out holy shit. There was one thread discussing bans for “orientalism” where people were going on about westerners being racist without any hint of irony (that was also where I found out the .ml stands for Marxism–Leninism). I deleted my account there straight away.
At least with lemmygrad.ml you know what you’re getting into…
I think it’s the way the algorithm works on Lemmy. I was on Lemmy.ml for a bit initially (until I found the tankies…) and yeah the front page didn’t change much at all even federating with other Lemmys. But I don’t think it was from lack of content. When I switched to Kbin the posts would cycle much more frequently and since Kbin enabled federation it’s really felt like there’s enough here to replace my Reddit scrolling addiction.
