Would Google ban my ip address if I signed up for a few Adwords accounts using those links which give you $50 credit, and a VCC?
Hmm - I don't endorse it but if you use different account names, cc #, etc. You "might" slip in under the radar.
this has happened to me beforeas i was trying to get the 50$ voucher for the second time using the same IP and the same CC I did not get any dollars in this new account .
I think any question starting with "would adwords ban my account if..." usually will result in adwords banning your account.
Just follow the rules. If you are serious about making money online with Adwords, then don't mess with Google.
