Ok, relativly simple way to do this, Firstly get a P2P program, not going to link one as theres 100's out there, this is just a small sample of what you can search to get keys, Ill take limewire as an example. What you wanna search for is Glider.config, This contains the victims glider key, i have a notepad document with 13 glider keys that arnt mine, and 3 are elite. Its not just limewire, any P2P site that lets you search for document's perficically XML documents will yeild results, if you really want a key you can get one within an hour, Best times to search are 5 pm when everyones back from school / work.
Also a free tip to all you gliders, never put your "Glider" folder in things to be sharded it contains ure key.
This is just the outline of the way to get info.
Ill finish by saying, glider keys arnt the only thing stupid people share
(work it out )
