You forgot the attention seekers, those are big. The people who post pictures and say they're ugly. If you think you're ugly, then don't **** post a picture of yourself. ,-, Also, the people who post… more revealing pictures of themselves then complain loudly when people are perving on them or when someone calls them out on it. Picture threads are fun, but they cause a lot of disagreement and negative feelings. I personally don't think they're worth it.
I personally don't believe more revealing pictures should be posted to the public. But that's just me I'm a more conservative type of girl and thus stay away from dressing in a way that attracts unwanted attention.
If someone posts pictures like "im so ugly huh?" Just be like "fuck yeah you are" and that'll get em off the thread. Works well
