I have a promotional voucher code! I want to use this code. But I have questions: - I must to register new accounts and each account can only be used a voucher? - I get AdWords login multiple accounts on same computer? (of course, these accounts are using a promotional code) - Google penalize me if I use multiple accounts using a promotional code to promote a site? Thanks all!
The Terms of Service is clear: only one account. So yes, you will get banned forever (and I do mean forever) when (not if) you get caught. So don't be stupid and try to game Google in any way. If you're a serious business person and want to advertise on Google, open one account, use your voucher, learn the system and follow the rules. In the long run, you'll be much better off and happier.
