What the people should do (the ones who are thinking of paying) is do some research on jtags and hacks and become more knowledgeable so they can ask the *possible scammer* questions about hacks and find out if he does his homework too or if he is legit.

Also if you ask for proof and the guy says ok wait and he takes several minutes to invite you then he is probably trying to get in an infected lobby to act like he has proof.

One more thing.
You can only use SUPER JUMP if you have a JTAG so ask to see that because that cant be infected.
