DC duplicated
 

I was recently (2011-12-12 23:21:46) assigned the DC of [URL="http://www.mersenne.org/report_exponent/?exp_lo=25226923&exp_hi=&B1=Get+status"]M25226923[/URL] through GPU to 72. I reported the result today, (2011-12-28 21:53, noticed by GPU to 72 at 2011-12-28 22:33:43) and discovered that the double check had already been completed, by "SADMASTER" on 2011-12-19. All 3 of the residues match.
I was wondering if this was the result of something like an accidental unreservation, or if this was just pointless run-of-the-mill poaching. chalsall, did anything interesting happen in the history of this number, e.g. it was previously assigned and unreserved? Is "SADMASTER" a name of a GPU to 72 member?
