I know for many, vote buying is about visibility,
The sad part about that is, that the more people use bots, the less it works for visibility, as everyone else is also using them, and you have to keep outbidding the other people on the top of the trending page.
And as time passes, people realize posts on trending are all there due to bots, so stop visiting trending/hot, like I have.
BTW, I wonder if seeing a post with very high rewards also leads you to upvote it less often. I know I do that.
100% to pretty much everything here. The main trending page? It is a joke. Proof of brain? Please.
