Friend Ref. Whoring. Question

[dibbs]

Bout to have to pay for some expensive ass textbooks which is gonna be just lovely, and with other bills and what not I'm trying to squeeze out every single bit I can, so I'm referring a bunch of friends to different sites that usually only play party.

My question is this, for Empire, if I get my buddies to set up an account there (under a clean computer)even though they have a party account, could that come back to bite me in the ass TOS wise or anything?

Thanks for any insight.
