Frankly, I have no background on Bitcoin Magazine, so my response will be limited to this point:
You also acknowledge that your account is personal to you and agree not to provide any other person with access to our websites or portions of them using your user name, password or other security information.
Since the site mentioned that the account is personal and it is not allowed to give your account to another user, it immediately means that the user is allowed to create one account and not more than one account, which is decided in the hypothesis of this theory is the IP address restriction if there are any restrictions on creating more than one account from the same IP (which should be) then you shouldn't.
In general, there are better ways to waste time and earn more. I advise the user to at least learn a programming language.
