Correct me if I'm wrong:

1. The incentives of this site reward participation in polls more than they reward "voting truthfully".
2. If there are fewer votes than reward shares, then the incentive is to sybil attack using low-sat addresses to basically guarantee a reward for each address/vote you submit.
3. If there are more votes than reward shares, then the incentive is to back your addresses with more sats to increase your odds of getting rewards. Rich-get-richer.

Therefore the value of these polls to non-voters (casual observers) is insignificant since there is no skin-in-the-game behind those votes. This is more like a complicated raffle than a truth-telling-machine.
