Giveaway winner

So I just won the halo 5 giveaway which I am super hyped about, but I was wondering about the w-9 and having to put in your social security number.

@Mohamed_Ndiaye Congrats again on winning the Halo 5 Sweepstakes! And I believe we just responded to your email about the W-9 form. Please let us know if you have any other questions.

Alright, thanks so much.

Hi Mohamed,

Could you tell me why you declined the Halo prize? I am in second and i just wanted to get a better grasp from you why you didnt accept it.

Cause believe me, the W-9 has me skeptical too

Hi I just won the Ps4 sweepstakes can anybody tell me how the w-9 form works ? is it safe?
