UID is used to develop SID for each player and as it is unique, both UID and SID I doubt he managed to crack the algorithm of SID making from UID. Also I believe BP uses 3-5 such algorithms therefore we got ourselves a lucky spammer. In case they aren't using such algorithms then UID is equal to 0 because it is actually the counter that differences players by date of registration.
But anyway, he might be an excellent hacker, case in which he would hack BP servers through a remote exploit, get root access using a local one, drop 10-20 admins which are logged in, search for the UID and then extract the logfile from the database of that UID. Give you any info you want for that account. HAHAHA!!! Veeeeery sci-fi.
You my friend are a masterpiece, in the bad way.
