Therefore, @Hhampuz and @Royse777 must compensate the company for the past weeks or at least pay to developer (out of their own money) to create a bot to verify that users in the campaign do not modify them signature during the campaign period, any modification will be sent to the campaign manager.
What? 
There's no obligation for both of them to compensate the company for the past weeks, they're not have any intention to scam the company and Shan85 isn't their alt accounts. I also don't think they need to pay a developer to create a script or adds on to monitor their campaign participants.
I think if someone want to move to other campaign, he need to let know the campaign manager by notifying through the previous campaign thread, so the campaign manager will remove his name.
But this forum have a lot members, I believe with so many eyes, this case would have very low chance to happen again.
