This is what happens if a certain individual was part of a campaign but nothing to do with the type of project, just for example is that. If anything that doesn't really concern him but still have to posts then he will, whatever the outcome will be. That's why some managers include this on the rules:
If you don't regularly post in the Gambling section, Don't apply.
Edit:
That kind of posts happens when a signature campaign requires x amount of post in the gambling section whereas these users don't even know what gambling is, posting nonsense just for the requirements.
Damn right.
You were just a few seconds ahead of me LoL.
