also with so many users the structure of the front page isn't much usable. Even when you joined i scrolled manually a bit to find you help and greet you. Nowadays it's a mess. People as you said abuse everything as well as the tags so let's go to the intro page. What we will see is that 80%+ of the posts are fake accounts, bots and people that abuse the tag so it's way hard for someone to find an actual newbie and greet-guide him.

In other words you join, mostly nobody greets you except some bots, you feel unconsciously that nobody cares about you so you become an abuser too or just leave the platform
