I rarely block people. I find it better just to leave Lemmy communities with problematic/annoying users… lemmy.world communities are the worst in that sense.

e.g. it might be me commenting in a non-political community about something random and then people jumping in and politicizing the thread and/or anything I wrote there. If I wanted to talk politics I’d join a politics sub, dealing with people that turn each and every post into something political gets old fast. And if the community moderators aren’t interested in moderating that shit then what’s the point sticking around in that community? So rather than block people I just leave those communities entirely & move on.
