...Bullet spammers on freeplay?

[DoctorShanks]

I've been playing freeplay alot today, and I've noticed that about 1 in every 4 or so runs, I come across a player that shoots like 4 bullets per second with a handgun, and their avatar goes into a spasm.

I instantly d/c against any player I see doing this (as well as anyone else using EXP/infinite item hacks...but thats besides the point ). I'm convinced it isn't legal.

But what I don't know is, is this bullet spamming a hack or a glitch? If it's a glitch, please don't post how to do it.
