If it is really true, then it is a big deal for bookies to deal with. That seems almost impossible? You could even make your work of this. I wouldn't be surprised if sites then decide to close your account one day.
The question then is whether you want to take that risk?
If the service provided by the OP is legit, then why don't he make money himself?
Why he is becoming so kind and offering the community with his greatest discovery?
Just make money yourself and move on.
Moreover the OP is saying us to cheat and which is according to me is not for the Bookies.
Better we should avoid these type of people and if anyone trying to deal with him, use ESCROW.
I answer on that few posts above. The offer is focused for people who have an access to the accounts (more than 1 or 2).
I would be really happy to use escrow to avoid any accusations.
