if you have formatted your c: drive, the situation u describe is impossible.
impossible is nothing... to begin with
if anyone does not believe me, just take the time and make your own conclusions and don't treat me as if I was dumb-stupid, I know what I say. At this point I believe the only way they ARE doing this is by grabbing (somehow with actionscript or maybe a hidden script on another web scripting languaje) some hardware unique id's, like the cpu one or the hard disk one, or maube a combination of both.
by the way, I always zero all data when formatting.
Dude, ive been on this forum a while (near the begining) and ive seen the n00biest n00b posts, posted by a n00b who studied n00b at the university of n00b, yet the regulars on here are 99% of the time polite and point said n00b in the correct direction.
Now im not saying you're a n00b but the tone of your posts is testing said politeness. Most forums would have told u to where to go after the "is it so hard to understand?? " comment. But people still replied in a polite, if not slightly blunt, (in response to your tone no doubt) fashion.
So chill winston... and maybe we can get to the bottom of this.
