I did raise a ticket on November 30 via their website support system, no response from Yobit so far.
I did the same yesterday, and tho I certainly don't expect a response from them I figure at least I did something and *maybe* they'll see it. The more participants that do the same, the better.
From what I've heard, Yobit often had problems with delays, but total disregard for campaign participants looks at least not nice.
No, it's not nice at all. It's disrespectful toward the members who have been helping them advertise cryptotalk.org and their indifference is baffling but not surprising, given their history. I'm not interested in joining another campaign right now, so I'm just going to keep wearing the signature and hoping for the best.
