It's not spam, despite what was said by yahoo. These are legitimate complaints right now, tho it might not have seemed like that a few days ago. It's been a week without payment and there's been zero communication by yobit to the campaign participants or to yahoo for that matter. If you think this is spam, don't visit this thread and you won't have to worry about it.
I do not think we need 30 different users saying the same thing over and over, which is what was happening. The balance is empty and Yahoo said there is nothing he can do other than wait to see what yobit does.
One user updating on the situation/when (if) they ever refill the balance is more than enough. Other than that, I would call 90% of these posts useless/spam.
They are hoping that the campaign will continue but I doubt it's going to happen, I think they are now going to allocate their budget to Cryptotalk and will increase the rewards based on their ranks, since they already got a lot of members and have gotten their goals.
