Having multiple accounts on TMS is a violation of the
Terms of Use.
My options are to block the same IP from accessing with multiple accounts (which certainly isn't foolproof by any means, and could block some legitimate users), or to make a judgment call on a case-by-case basis (which can get tedious if the game really takes off at some point). Any better suggestions?
In the meantime, I'll just have to flag and remove accounts. And just so everyone's aware, I'm going to err on the side of being overly protective.
