I disagree. Spam starts with the spammer and is then encouraged by the signature manager. These users were spammers before they got into a campaign and they will continue to be spammers once they are no longer in a campaign. If we got rid of signatures and advertising entirely we would still have spam, so it's unfair to lay that problem at the feet of campaign managers. They're making the situation worse by being terrible at their job and paying people to ruin our forum, but they didn't start it.
