I think you have a valid point here. If there was a day when alt-accounts and those enrolling in campaigns using their account farms were expelled from campaigns, there is a possibility they will stop posting here and it will affect the forum usage. Let us not forget that competitor forums are increasing there user base therefore it could (in the long term) put this forum in a precarious position.
Keeping all that in mind, any form of cheating, rule-breaking and abuse should be discouraged at every stage therefore I am glad I am not the one hiring and firing campaign participants.
I cannot state either way about the number of account farms that operate and how many have multiple accounts enrolled but I hope campaign managers stay vigilant against abuse.
Let me take a devil's advocate role for a second and ask if its even in the forum best interest to remove all those that are abusing campaign rules with their alts? Removing those means less activity on the forum which then may cause fewer campaigns which then may cause less overall activity etc.
