I've been here a couple months and the insincerity is the first thing that stood out. There are people who share thoughtful comments and you can tell they're just trying to get a vote, but at least they put some time and effort into what they're saying.
The group that bugs me are basically e-beggars with lazy, low-effort "thank you for posting"-type content. It's like chicks fishing for compliments and attention on Insta, but instead of putting SOME work into a cute photo they just snap a pic of themselves laying in bed, messed up hair and face pushed back showing off the double chin.
