Good to see that your campaign is back. I am not sure if the requirements of campaign from your side, but seems require 10 post on gambling sections mandatory. Which might increase spam and you might get low quality post although this is the duty of manager for qualify post. Most of gambling sites require 5 post on gambling section and I think its appropriate. Or you might ask 6 but 10 really high in my opinion. All participant of your campaign doesn't mean they are gambler also. So its pretty much sure those are not much familiar with gambling they would spam here.

However, hope manager will handle it and select right person. I just describe my opinions, it doesn't mean participants are spammer. Hope you will not get me wrong.
