Hey Blackhat World. Need someones help Please. Recently purchased 500 PVA Yahoo accounts for $120. When I login in with username and password, It tells me, "You havnt signed in from this location before. It then displays a mobile number to verify the account, but the number is blanked out apart from a couple of digits. Whats wrong and can anyone advise. Have I got ripped off. Im new to email marketing. If anyone can help I will give them 250 aol email accounts that I know work.
