About Polls (Patreon)

So I was talking with folks on discord about the poll and it came to me that ppl could cheat about the polls, Like make 10 accounts on patreon and pledge 10 times 1 USD and take control of polls. And I thought it would be good to give more power for those that is pledging  higher like Slime Lv 5 and Slime Lv 10  but I dont have total control of the polls on patreon so I thought in doing this: The idea was to make like multiple polls, 3 to be exact:

1 poll for level 11 poll for level 5and another poll for Level 10Lv 1 poll would count as 1 for each voteLv 5 poll would count as 2 for ea voteLv 10 poll would count as 3 for ea vote

also Lv 5 Patreons would be able to vote on Lv 1 polls and Lv 10 Patreons would be able to vote on  Lv 5 and Lv 10 polls

What do you guys think? Is that too complicated?
