Are these illegal? Yes. Can they be revoked? Yes. I don't think so....
Are you serious? EVERY key shop here is involved in MSDN keys they just don't want to say it. I am open about it but ok.
I have used my keys for years and they have not been revolked but thats up to you.
Keys only get revoked if you sell the same key to a lot of people. If you sell one key to one customer it will never get revoked.its called common sense which sadly people dont have these days .especially the buyers
