I still visit Reddit occasionally for old niche tech support, but that's about it. Tried Voat but it was dead on arrival.

Here's a list -

Lose of RiF was the last straw.

Inconsistent censorship.

Mods targeting users.

Promoted ads disguised content

Hive mind comment bombing and down voting

Lack of understanding or reason

Gatekeeping by mods and users

Spam bots

Achievements and robot challenges

Reposting/resharing the same memes over and over like it was new content.

Reporting posts didn't seem to do anything
