umm, you say in your own words...
"if they find out about this giveaway, how will they know exactly what keys im giving away?"
Umm that little pic up there shows the beging 6 digits of ALL 14 keys..
If your a little slow and dont understand, all blizzard has to do (assuming this is legit) is look at thos 14 keys begging 6 Digits and ban thos keys, because the odds are there is NO other key that uses those EXACT 6 starting digits...
if you get what im saying, i'd suggest getting rid of the picture(assuming this is legit)..
P.s. I also think if this is legit i should get a key for the heads up LOL!
