My experience with abuse reports is... they rarely get listened to. Now I know why:
Chiyo Linden: (Saved Thu Apr 8 06:01:46 2010) Please stop spamming Abuse Reports. One a day is more than sufficient.
This was in response to several abuse reports associated with a PG orgy area. Clearly, Linden Labs view is they don't do anything to enforce their own rules, and they get very annoyed when people document that the rules are being violated.
I think LL is trying to set a new low for unresponsive hostile customer service.
