The only thing I can see happening is if people abuse their tribe referral links and spam other communities in a manner that exploits the concept. I am sure however that a few rules in regards to that can be established to prevent people from being bone heads.
This is how I think 90% of referral codes will be used. I hope I'm wrong.

For everyone's sake, I hope you're also wrong.
