How much do you think they have paid out to participants so far?
It is unestimated because we don't have a list of the final active members who participated in the campaign until now and also those who are leaving earlier in the campaign, if we have a spreadsheet of participants then, yes maybe. One thing for sure, there are thousands of dollars have been spent on that campaign a day. A

When do you think they will stop or pause their campaigns?
When their wallet was emptied.
As I remember before, they didn't pay their participants and leave the forum. Probably they will do it again(but now now I guess).
Apart from the obvious reason of advertising, what other motives would Yobit have for trying their best to entice users to promote them here in this particular forum?
Of course, Bitcointalk has good traffic than other crypto forums. It will give promotions to their site and might probably lure people for their invest box and other promotions.
Just my two sats mate!
