clearbell, would you do me a favor and re-post this in your journal? Not very many people read mine.
There's an "author" (and I use the term VERY loosely) who is spamming the hell out of fanfiction.net with duplicate and inappropriate posts. I don't think it has reached the L&O fandoms yet, but it may. The penname is "Whorepath's Griffen". Keep an eye out, and if this jackass appears, REPORT, REPORT, REPORT. ff.net might not do anything anyway, but they definitely won't if no one reports.
EDIT: On further investigation, I think someone's account was hacked. So in addition to keeping an eye out for this person, keep an eye on your account (if you have one.)
