Hmmm.... Well, I've met some really nice folks, and some not-so-nice folks.
The nice folks are great! They post things I'm interested in, and I'll post replies back. It's a party of sorts. I love these exchanges and it's what most people want on the net, even the new "wild west" of the Fediverse. I've found a lot of them on my Mastodon instance, and it's been a blast!
Now, there are the not-so-nice people. It all started when I blocked a bot because was advocating r4pe culture, then users from that domain/instance decided to troll me with racial slurs. I ended up blocking that domain. A few others decided to join in from other domains. I blocked 2 more users and decided to have my own troll-fest with the last one. I essentially used logic against him until he was just a sad puddle of a human being. I know it wasn't nice, but he wasn't very nice and left me alone after that. Maybe he'll seek the type of mental help he needs. I hope so.
Anyway, that's been my experience so far. I keep looking at my lemmy instance (where I'm posting now) and wonder if I should promote it even a little for a limited amount of users. Let a few hundred in and see what happens. lol
Stay safe, it's a jungle out there.
