I want to add a feature to my game of team contributions. Ie, based on what your team contributes to the pot, you gain a bonus based on the total contribution.
This, of course, is plagued with problems that stem from multi-accounts. If I want to be stronger, I simply sign up many multi's, dump all of their contributions into the team pot, and reap the reward on my main account.
Any ideas on how this could be prevented? Everything can be discussed from limiting team sizes, multi-detection, limiting the amount that can be contributed, etc.
