Submitting solutions using more than one Overmind account is a clear violation of our reward exploitation policy. We make it hard for solvers to create multiple Overmind accounts. Our current system restricts signups to Github accounts created before Overmind's beta launch on 01.26.2023, making it impossible for a solver to create new Github accounts in order to game the system. This system is highly imperfect, not least because it excludes solvers who are brand new to programming. Sybil resistance protocols are rapidly evolving, and we anticipate that there will be battle-tested systems to choose from in the near future.
