Nefarious users can create false alarms that must be investigated.  They 
can "drop" your host entries and therefore wipe out incredible amounts 
of RRD graph history.  If you have tests with delayed notification, it 
would be possible to prevent notifications on real alarm conditions.  
There are probably other nasty things I haven't thought of.
