I was talking about payout system, manually you have to check the posts and count how much people posted, update the sheet. Send payments to 300 people. But all this thing has been automated with Yobit, the only problem was controlling spam. That's why they hired Yahoo.
The system is actually bad, everything is automated and there is no control when submitting, paying or checking the quality of posts. Because of that, they need humans to repair all the chaos that YoBit system creates.
If everything is done manually the list of candidates would be much smaller, bad users wouldn't even get a chance to start spam. You are not too long in this forum, but few years ago there is more than one signature campaign with bot system, and spam levels were at least three to five times higher than today. Just imagine only one or two similar campaigns like this, what a forum would look like?
