There's no way thouse bounty spammers all have thousands of real followers. All they do is spam Twitter and Facebook, and they exchange followers with other bounty spam accounts. So even if a bounty spammer uses only one account on Bitcointalk, they're still cheating with fake followers on social media!
I agree with you here, even though you may have wanted to say this politically correct. I would say that the biggest blame here comes from bounty managers. They try to have as many participants as possible, but the quality is completely neglected. even ignoring the negative feedback on the profiles.
somewhere in the past (at the time of ICO), there were some mass campaigns that brought in good money and based on that, all managers took over the template. the same thing has been driving for five years, just different names for "projects".
so the question is if you are one of the top groups and start a business, would run a bounty program like these currently running?
