I've been here for sometime now 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.
