There are three accounts from my ip, and never have a single problem. My sister , me and my brother using 1 account each, so if i can't use three account from 1 ip mean three of us have to share 1 facebook account ? Ridiculus.
I'm sure that Facebook is a little bit more advanced then saying oh three accounts from one IP ban it. You would see an uproar across the Internet because many businesses use static IP addresses. If they had 50 employees who all used facebook, they would all be banned. While its not allowed by the tos, in good intention from a business standpoint you would separate the accounts. You place yourself in a liability with having person crosss business that is more costly then facebook banning you.
It's against the TOS, but you can easily make additional accounts. You just need separate emails. Many people do it in order to play certain games and collect stuff.
yeah you can have as many accounts as you want, it's just based on the number of emails you have. You can even setup a couple of hundred emails on your domain (1@domain.com, , etc) and then use each one of these for a seperate account. They don't really care unless you start mass spamming or something then they'll boot them all
It might be a little more obvious to them if setting up all the accounts on the same domain. If it is yahoo, google, etc. that is a little different then a custom domain, in a numbering pattern.
