I dont know if this idea ever crossed your mind so i will explain to you. It is very simple. Once both you and your trade have completely agreed on trading accounts:

1: log on to your account
2: stay on until after cash is handed over......
3: if the guy tries to scam you and dosen't pay you, all you need to do is change the pass before you log out

Ps: make shure you are already logged on to your account on the runescape website and in the change password section...

I dont know if this trick will work.. never tried it or never read it on sythe so throught i might post it..

good luck.....

 

If you are on the account, he can still change the password.
Also, this is the wrong section.
