I have to open up multiple Gmail accounts (3) to be used for my domain one each other, i.e. , , etc. Is it not against their TOS?
I see most of them use it for spamming because they don't have to have responsibilities for any problems they have caused.
No, these accounts I'm going to sign-up is not for spamming, I hate it myself I decided to use Gmail because I think it's more safe than using with my own domain. Plus, using my domain for email is a little bit of hassle when I transfer from one host to another.
I don't think it's a problem - I have a whole bunch of Adwords accounts cause I switch from one to another when using adwords vouchers.
Nothing to worry about using multiple Gmail accounts. Gmail has a email forwarding option, this means, they already know that people will make more than 1 account Anyway, you can't have more than one adsense account.
