yucky...
oki i agree with cyberus on this one to some point, but why would he accept the amount 2 times in a row??, paypal doesnt auto GET big payments and the person who get the money has to go and recive it manually (on the website and the move it either to her/his account and then forward it)..
all in all it might just be a mistake by the seller and i wish that this is the case but i have a very bad feeling about this so please understand my "hasty conclusions" ..
anyway good luck on this guys , and to trace an ip , use NETINFO for this..
cheers
