If you are worried about duplicates, aka a single bot spamming multiple votes, then that’s feasible to mitigate.

If you are worried about multiple bots spamming one vote each, that’s harder to mitigate and it comes down to how the instances handles bot accounts in general. IMO it’s best to ignore the bot problem and instead focus on designing a vote weighting system that favors similar instances.
