The user that Mahdirakib discovered wears a 1xBit signature. He is already tagged and I doubt he would care about more red paint, or neutral in this case. No idea how many other users there are or how their reputation is. It surely is a type of abuse, but since theymos doesn't want DT members to tag people for merit-related actions, (unless we are talking about buying and selling merits) I would check with him before doing it.
