I agree. My Reddit outrage addiction flares up every now and then and it makes my mental health objectively shitty. Doesn’t matter if there’s some good content and connection on there, it’s just not worth the (mental) cost.
Reddit is overwhelmingly fake information and covert ads. Investigate any random post on the front page of /r/all, even if it's just like a cute gif of an old person, then go to the comments. Like 75% chance there is something fake or made up about the title or context. It's such a mind pollutant, I can't stand it.
In my opinion reddit is still such a great community if you subscribe to topics that interest you and leave the default subreddits. There's plenty of subreddits that I would not be able to find a good alternative forum for, maybe a Facebook group exists here and there but is that really better?
This is to be expected for /r/all. But who cares because why would anyone want to go there in the first place? In general once something becomes a certain size wrt users, its value to those users plummets. The only thing to do is leave.
