Are these VCCs or paypal accounts cracked?
No. They are not. I create them by myself and there's absolutly no problem with that.
Can I get limited with the account?
No, only if you put more than 80$ in 1 payment on the account. If you use it carefully, you will not get limited.
VCCs work?
Yes. VCCs really work without any problem, you can use them in websites like Ebay, Amazon, Paypal, etc...
Have you ever had any problem with selling paypal accounts or the VCCs?
No. Never had any problem with any custommer, so I think it's a good deal for both, buyer and seller.
