The following was my experience.I politely talked about a bad experience I had on a chess website (lichess), which accused me of cheating, which I never did (curiously, it happened right after I attacked a friend of the site managers). I wanted to see if anyone had my experience.Lots of bullies came to insult and bully me, despite the complete lack of evidence against me (that site system works like this: anonymous moderators make public accuses against people without sharing any evidence, not in public nor in private, which is quite unethical I think).One of the worst bullies, one who literally insulted me, was a very respected and active reddit member, and if I recall well a moderator as well. I think I said more than enough. Online communities are all bad. Reddit's one is ESPECIALLY bad. Not to talk about how the site is managed. Despite being kind and polite I found myself with negative karma and unable to answer. There's no freedom of speech, write something people there dislike and you're muted. Instead, insulting and bullying is completely tolerated as long as the community likes it.
