Excellent thread.
No one is entitled to be in any campaign unless a manager says so.
Joining a campaign is a privilege, not a right.
This times 1000. It seems that many half-baked posters, spammers and whatnot seem to think that they are somehow entitled to enroll in campaigns. However, this is most certainly not the case and this mentality needs to stop.
I also want to send a message to some of you 3rd world users. I'm sorry you were born into the life you have, or live in a poor area of the world. That's not my fault.
I've had some of these cases before. Those are usual logical fallacies (e.g. appeal to emotion) and should be ignored. Signature campaigns are not Caritas.
