>>4340891>Lol imagine tolerating shitposting on 80% of your board's threads.
Yup, that's how 4chan works. If they don't make it extremely apparent that they are only pretended to be retarded instead of actually being genuinely retarded, it's not breaking any rule. Quality posts aren't required, just like the post I'm replying to.
There are other sites which don't tolerate low-quality posts, at the cost of restricting how you can express yourself. Finding a balance that works for you is a personal problem. Personally I lost interest in /g/ around 2015 once I got a career in 'puters.
