Moreover, we are talking about something that is getting a bit more dangerous when a place tries to do marketing that way. They obviously had enough money to attract people in regular marketing, but preferred to overpay for signature campaigns, that means not only they expected you to promote them, but also say good stuff about them as well.
However, I have to say cryptsy exchange was one of the worst probably because of what happened. After mt.gox turned out to be a scam, they got almost every other investor, and people were trading there all the time, then they stole all of our money. That was the second biggest scam and I missed mt.gox days but got hit by cryptsy.
