Aha! So there is something unseemly going on in the Ivory Tower.
Heh, actually yes. There has been some testiness on the astronomy lists, and a number of folks who are rather displeased with the behavior of Brown's group. Brown is trying to take control of the situation, including taking the discovery claim away from the Spanish amateur. Most of the other folks are having none of it since Brown did not catalog the objects in accordance with the rules he and all the other research groups are nominally playing by. From everyone else's perspective, if he got burned he deserved it.
Even astronomy is not immune from petty politics. :-)
