It would be interesting to know who that person was, if not a brand-new throwaway account.

Why are they asking you to where the signature and not use a signature space of their very own account? It tells you why. Because they know it's something wrong, or they are trolling.
I think it's just someone unhappy with Royse777 since he is a campaign manager. Maybe some past grudge from signature selection or envy. We have different kinds of people here, so not surprised.
