Feeder Towns?

I don't see how EA could possibly police them and identify feeder towns if they are being linked to separate e-mail addresses with separate Origin IDs. Even if they could identify multiple towns being played on the same device, they wouldn't be able to distinguish a person playing multiple feeder towns from multiple members of a family all playing their games on the same tablet. I'm guessing feeder towns would be much more of an issue in games that are more competitive between users - Tapped Out is much more of a cooperative game than a competitive one.

I haven't bothered with a feeder town as I spend too much time already just playing my one town! 8)
