I don't think I can see more info on voters, or know how lol

i believe you can filter voters by people you follow and lists or something... apparently.

i don't really mind, it's just a bit of a larf innit

So your Id gets stored locally, just clicking on submit should not add another vote as is, but you can easily spam by doing so in incognito.

For non spammy polls the poll creator should set a proof of work difficulty, or the poll viewer should filter the results only from the "people they follow" or any lists they might have added.
