Rather sad way to live, but more importantly -- the slowness with which LL seems to respond (if it does!), would only encourage more to abuse. This will increase the abuse report, slow down the process further and more of the normal people will get tired and leave.
One way to reduce the abuse is for LL to act more promptly. That would, IMO, make people think a few more times before abusing resources, permissions, rights...
Just a thought:
What if LL actually reported aggregate statistics on a regular basis (weekly, daily, ...). Something like:
# of Abuse Reports, # investigated, time to investigation start, time to resolution.
