PERP Money Exploit??

I was on this PERP server and some dude named "default2" kept joining and spawning money/duping money. Anyone know how this is done? I tried adding him but it said error.

it was a ghost oo

Lols Code <3 It sucks you're banned but it was nice having you here , I know of the exploit I will see about releasing it I don't really want to due to if i did everyone would abuse it.

Whats the server IP? I bet I could do it for you.

Can I come with you <3 We could prob do it togather and be the riches mother fuckers on there
