Just wondering... I know FB support isn't the greatest, but have you asked their support why your account is blocked?
Is your page personal or commercial? If it's commercial and you are sending out random friend requests and requests to "like" your page, under their Community guidelines, you are spamming and that would be the reason. If your page is personal, the only reason I could see it might be blocked is that one or members have reported you for harassment, the definition of which is repeated unwanted friend requests.
