Examples of ideas we most likely won't do:
Here's decentraland's agora: https://agora.decentraland.org/ And of course, there's a blockchain for that! https://www.agora.vote/technology
But more seriously:
Voting is a tough problem to solve. How do you avoid spam/bots unless the votes are tied to users in some way? Also, how to handle exactly-one-vote-per-user-per-poll? How do you handle the equivalent of ostracising bad actors from the process (maybe not as extreme as the OG-way of banishment for 10 years, though: https://www.greece-is.com/understanding-the-agora)?
Maybe some system that involves (some service or the mods?) privately pushing out (via DM?) a one-time-use code (UUID?) for casting a vote in a poll once it's got enough weight to be put to a vote? OTP SurveyMonkey? Is there some way to prevent back-tracing of the vote-codes/tokens to individuals? If someone becomes a problem, then I guess they just stop getting vote-codes pushed to them. Slippery slope, etc. etc., though.
