The Elder Scrolls Online key from the Alienware giveaway

Let others know if you claim it

It's already claimed, why do you post keys like this????????? Bots just activate them in seconds

In future best place to drop a key is:
Orphan Key Drop thread - https://www.steamgifts.com/discussion/hK2kQ/
Anti Ninja Key Drop thread - https://www.steamgifts.com/discussion/tnWVh/

That code you posted was likely instantly snatched by a bot, posting it in either of those threads with some slight alterations (math puzzle, etc) or saying you have one and first to message you gets it, is the best options.
