erm... ok... going to bring this up one more time... It's been implied before, but no one's come out and said it...
THIS IS A GAME. SOME PEOPLE IN THIS GAME ARE IDIOTS.
There is no easy answer to your problem, but as with some of the previous reports, stop setting yourself up as a victim. Is it fair that you have to make changes? No. Is life fair? No. Decide what you want out of this GAME and act accordingly.
1) STOP sending in abuse reports - obviously they aren't working to your satisfaction. If you're sending in that many, then I can see why. Like it or not, as soon as you get a "reputation" for being "judgmental" (note the quotations before you flame please), your abuse reports may well be "de-prioritized".
2) LL gave you a mute button for a reason - use it. Mute the ijits, have done. Run a HUD or a viewer that lets you be no-push (ie - "phantom" in emerald) and ignore the buggers. If they show up, put your avatar on no-push by whatever method you like and go make a pot of coffee, vacuum a room, take the dog for a walk, take yourself for a walk. Better yet, make an alt, log your main into where-ever you don't want to be and go shop/visit/whatever on your alt LOL.
YOU are the only one who can choose to not be a victim in this situation. They are the only ones who can choose to leave you alone. The one advantage between SL and RL is that in SL you DO have some options - if this were happening to you RL, you'd have a much tougher time coping with it, as you'd have fewer options.
Lastly, remember that they're ijits, pure and simple, bullies who never grew up to be capable of accepting their responsibility as adults with the rights, privileges and duties incumbent thereto. They are incapable of growing as the only way they see to make themselves feel big is to make someone else feel small. Pity them, and most importantly, AVOID them. They're probably not fixable, and if they are, they'll need to make that decision for themselves, should they ever be capable of doing so. Until then, they'll drift from sim to sim and possible victim to possible victim, trying to find some sort of fulfillment for their small lives.
