I don't know how much exactly are the bounty hunters owed but their bumping service has been paid/renewed as of 27th this month after having a three-week pause. Both announcement threads (BQT and IOU) have around and over 100 pages x20, that's 2000 give or take fake comments each (more than 95%).
I visit BQT thread, and post about how participants of their bounty did not get pay for they work, but no reply on that post. They just continue to post nonsense posts which just proves that these are paid accounts. Maybe teams reacted on this thread, and that is only show they use suspicious methods for the purpose of promotion.
