A friend of mine created a website where you can go, put a trial key for world fo warcraft in a form, your email and select the region of your key (EU/US). You wait, (I waited 3 days) and you get 6 (5 plus the one you already had) working
wow keys.
I didn't believed. But I saw the code he used to exploit blizzard and get the codes without trace. He has 2 scripts, one for US other for EU. They wait for a time with more players, when the server is very busy. Then they start injecting lines and lines of code (seriously, I'm a programmer and I can't figure out how he did it) and a few hours / days later the script returns the keys to an email, cleans traces and selfdestructs.
this is almost perfect. blizz will take ages to find out how this is done.
by the way, you may find strange that my username is the same as the root of my site: chalkos.
that is because i'm hosting the site for him... he didn't found a script to create free hosting accounts for lifetime... yet
