Out of the open platforms, I use:
Reddit: Lemmy, Beehaw, Kbin
Twitter: Mastodon, Calckey
Facebook: idk nothing really plus I don’t even use Facebook that much anymore
I may occasionally use proprietary ones like Twitter, Tumblr and Threads.
“Third reply downvotes” and other types of bullying done for absolutely no reason. Also, people misleading others to disgusting communities just to troll them, for example (and I am paraphrasing the names of the communities): “misspell the community’s name to c/vercute instead of c/verycute and you accidentally get a sub full of gore” or “check out c/audioing, it’s definitely not people doing a very disgusting thing to one of their body parts”. I do, however, like the fact they’re bringing the whole subreddit swap meme - for example: on Reddit we have had r/trees and r/marijuana_enthusiasts and I’ve seen that implemented into Lemmy instances already. I wouldn’t get rid of that, I think there are some traditions that are neat and don’t harm anybody.
