This will never happen because you are not a janitor, and even if you were you would not be the only one. This is out of your control and being against cooma booba spam 24/7 is also an unpopular opinion on this site by now, so the only thing you can do at this point is leave the sinking shit and form another community instead of enduring day after day.
It will not change, you cannot expect others to "fix" a large community that has gone to shit on the internet. This is why the internet as a whole went to shit, people want to be on the big site where common sense needs to be replaced by broad arbitrary guidelines in order to integrate as many people as possible, then the guidelines become more and more lax so that the place grows bigger and the place goes to shit. It's as predictable as physics, it's only a matter of how fast. If you feel alienated then work on being part of another community and accept that this community will not be as big as the big site. 4chan is a big site, it's the public toilet of Twitter and Reddit just in case you didn't realize.
