I didnt come across any of those hidden section , yet. BUT Im really new. Paypal on steemit sounds really uncool, I have to admit.
I just feel like a few people "forgetting" to upvote is not as bad as having posts I have to upvote to read. Radical example would be a political discussion where somebody has an opinion that I absolutly not agree with and do not want to support. I stil want to know his arguments, so I can argue against him, but I dont want to pay him for that.
