Thank you :). Absolutely, I hate the Follow for Follow / Vote for Vote culture and it is a culture that stems from Youtube and any other social media platform where content is monetized; Unfortunately people have this belief that if they gain enough 'Followers' or 'Votes' that they will suddenly become popular and have the "Easy life of Internet dollar dollar bills yo".
In Reality though things could be further from the truth, the easiest explanation as to why these 'schemes' do not work is respect; our whole human culture is centered around respect and we only watch and like content consistently if it's by someone we respect. People who ask for followers and votes don't realize what they are doing is actually permanently damaging the respect anyone would have for them, as if you don't respect yourself then how the hell else can anyone respect you?
In terms of it "sorting out", I'm not sure it ever will. All we can do (and I do this whenever I see a spammer / someone who begs for follows/likes) is flag and make sure that spammers/beggers do not clog the system and remove visibility power from people who have legitimate and good quality content, (And also make sure that spammers earn $0 on this platform and so are dissuaded to use it).
I do have an example of a group of the community 'Sorting out' a 'bad' User, if you look at @ivylifestyle You will see a classic example of a horrid spammer who now (due to me finding and flagging him as well as others helping me out), from a lack of reputation cannot post and has effectively had his account "destroyed".
