Looks like the Mods are sleeping late today. Lots of flagged posts haven't been deleted yet.
On a more serious note, if Admin will send me a list with Username, Location, and Drives of users who have signed up in the last few months, I'll see if I can find someone to write a short script to GREP loc and drvs for the "aaaaNNNN" string (or do it manually). Should be able to spot most, if not all, of the SPAMmer accts.
