Seems to me you are doing important work here!
Since we are part of a decentralized ecosystem, it seems to follow that many might use polling as a way to arrive at various degrees of consensus... for example for directions to take, and features on apps, and so forth. And so, a polling system needs to be as "robust" and resistant to manipulations, as possible.
Allowing the results to be filtered while everyone can still vote seems like the superior approach, as it will help expose patterns (if any) that suggest "bad actors" attempting to manipulate...
Nice work!
Adding your witness, as well.
Thank you for the witness vote.
