Yeah it has been rough. Decade and a half old account, frequent poster, moderater, went out my way to be open minded.
Never a single ban, until two years ago:
One ban for catching someone lying, they were friends with the moderator I learnt later.
One ban for crypto facism I think it was? Why? Explaining to someone what a certain right wing political faction in the uk was and the upside to them being a protest vote to put pressure on current government to do better. Not even my views, was just devils advocating for someone elses opinion.
For reference I'm a left leaning libetarian, there was no argument involved, just a zealous moderator who seemed really young.
A ban on privacy sub for replying to someone who said something political, tbh, fair enough, caught a stray as did others yet can't fault the logic, just the punishment (perma so hot right now)
Last was on a literature subreddit where the moderator made some questionable changes, I and some others politely discussed the changes, were upvoted for it, that ruffled mods feathers and so we all got a permaban.
When you become a moderator on reddit they give you resources telling you how to act, what the goal is, etc
It became abundantly clear that reddit doesn't care to enforce that. It's all just words to feel nice.
Echo chambers, ragebait, tons of bots and fake interaction.
I just had to find an alternative and here we are. You can tell the quality of discussion is so much better here.
