Later last year, I did notice an uptick in Lemmy hostility, across the board. It’s calmed down significantly, though, around January of this year or so. Now, I don’t know about the instances that my home instance blocks (hexbear being among them, thankfully). I’ve generally had good experiences with infosec users in the past, which is why I moved instances to here. Sorry that hasn’t been your experience; people can be assholes.
