Recently won a (as of then not yet) exploited game, what to do?

Its not exploted really, it was just an IGNPrime thing that people gave away keys for so Steam would be expecting an influx of "a virus named tom". I wouldnt stress.

No its not exploited, it was a key obtained for from IGN prime.
They are %100 authorized and you won't get banned.

It it somewhat strange though then if it is not exploited why the Gifter has been suspended and then banned form steamgifts. Another user told me there was even a thread threatening suspension for those using some ign exploit.

AVNT keys were also exploited.

Those keys were not exploited. yes they got them probably from IGN but they are legit keys and steam won't do jack.

Just found that

credit card fraud sounds pretty serious

I was given a key from a friend. They key was later to be determined as exploited or something and was removed from my steam library with no consequence to my account. You shouldn't have any problems.

Those things are such a shame... AVNT developer was kind enough to give a lot of keys for free on reddit. I wish them well.

I guess to be on the safe side i will submit a ticket to steam stating my suspicions and asking if they can verify the key by some means.

Would anyone know how i can get a linkie to the giveaway i won? (the link in the won list disappeared :-/)
