The only difference between LiveCoin and YoBit that I can see is that Yahoo is presumably receiving payment from YoBit.
It is disappointing that yahoo is not receiving the same pressure to close the YoBit campaign as Hhampuz received to close the LiveCoin campaign.
There's something we are missing I think. I was a little active in the cryptotalk forum and what I observed that, cryptotalk isn't a forum from Yobit. It's certainly a different company who wants to build an active forum. They are using Yobit for an easy payment, less work, no one to trust. Since Yobit is an exchange, certainly they will not commit fraud with the fund.
So, there's no problem with managing the campaign, cryptotalk has hired Yobit, yobit has hired yahoo.
Yahoo is not directly managing the campaign, participants acceptance is automated, anyone can apply even a lower rank member. But once they are found spammer, when yahoo check manually, they are being removed. It's not an easy task to get 100% qualified participants within week, right since the acceptance is automated.
My two weeks signature management experience-
I was trying to get the best promoters, quality posters although the pay was low. But out of 0.03 BTC budget in 1st week, I was able to spend 0.018 BTC which can never satisfy my boss. If yahoo goes with same strict rules, he will not get more participants as per budget. May be he will be able to spend 20% of the budget. What will you say, yahoo is incapable or bitcointalk has low good posters (which refers lack of real interested person). As well as the cryptotalk owner will certainly be not happy and recruit anyone less capable of mamaging spam either.
Once again, the main point is, no one promoting yobit here at all.
