I would think with a handle that is the SAME as the "notice of race" being posted, "would" tell most that this person is probably "paid staff" or at least some high up volunteer! Not sure they really need to go to the trouble of the relationship in sig or equal!
Worst case, one could call this SPAM, but reality is, it is a notice of race by the owner/sponsor of the race. Pretty cut and dry when I saw it this morning.
