...If the user who marked him is on DT1 or DT2; staff; or any other list to be decided, then the marked user losses the right to wear a signature. This way, it's not up to signature managers to allow them into a campaign or not. The forum would disable the signature for him...

Some details should be discussed, but that would be the idea.
But, but! *insert complain from a shitposter*: The DT1/2 members can't participate in a signature campaign themselves, or it is obvious abuse!!

This is the kind of bullshit that that suggestion will receive, although I like the idea (something similar was proposed via bans a long time ago).
