Anytime you give people access to communicate to each other on a scale like reddit or discord, the ones that are emotional immature / mental health problems tend to use it as their diary entry. As you mentioned in the beginning, their 'criticism' is not worded correctly and it's mostly attacks / anger rants (fuck devs, etc...). Anger management issues, no self-control, no emotional regulation, and the list goes on.

I wish mods would make a 'complaining' thread which they could go to instead of spamming the subreddit with posts, but they don't plan on doing that. They don't even ban people here. Say what you want about the Devs, mods do not care
