The problem is that you simply don't trust or think the worst out of the other people around you, or expect everybody's standards to adhere to your own despite going to a thread where everybody just wants the same thing, fart porn. What kind of person thinks that people just posting an image is antagonistic unless they're taking it personally for no real reason?
In the end it doesn't have anything to do with an objective standards, because it's not like people are posting stick figures with a spray effect, or people coloring outside the lines like a children's coloring book. one of the more popular artists that even got dumped for a half a thread has a same face problem and imperfect shading, and some artists that used to be posted are straight up not great but they've gotten better or people still like what they're putting out anyway.
Just trust that the 30 other people in an anonymous thread for farts are all after the same thing and are assuming what they're posting is decent enough, rather than trying to be at each other's throats over random bullshit.
