I have to admit that I am surprised that you who have been on the forum for so long think this way. The goal of plagiarism reports is to permanently remove such users from the forum, not just remove them from one campaign signature only to then become participants in some other campaign. Given the low entry criteria for most signature campaigns, I'm sure the user in question would find a new campaign very easily.
This is nothing new that I have not heard from some other old members of this forum, so although I think this is a wrong attitude, let everyone decide whether to ignore the problem or try to be part of its solution. You forget that it is no longer easy to progress in the ranks since the merit system existed, so anyone who tries to create a new account and plagiarize and spam again will not progress far.
User permanently banned.
