Same winner(s) listed twice consecutively

[adheeshparelkar]

Since the last few raffles, raffle bot has been randomly posting the same name twice.

Example 1: https://talk.vanhack.ca/t/welcome-to-2025-raffle-2/16006/11

dbynoe has been listed twice as number 9 and 10 for 21x Koonie Air Duster.

Goatwind has been listed twice as number 8 and 9 for ~10x Onevan Chainsaws

Example 2: https://talk.vanhack.ca/t/welcome-to-2025-raffle/15977/6

Eviickaaaa has been listed twice for 23 and 24 for 1 x IPEVO V4K Ultra High Definition USB Camera

I'm guessing this might be todo with the paging update.

First I instrumented the get_all_voters and was able to reproduce the first example (dbynoe for Koonie Air Duster). I reverted to the old paging implementation, and surprisingly got the same result.

I then manually checked the API requests/responses to Discourse for and I find that he is in fact returned twice. So I would conclude that this is not an issue with the paging logic on our end, but rather it's something like a bug in discourse, misuse of the API, misunderstanding of how an individual can "vote" twice for a poll, etc.

Here's the repro:

curl --request GET \
  --url 'https://talk.vanhack.ca/polls/voters.json?post_id=87127&poll_name=poll&option_id=4792f70da4aedcf4df07034901f70e77&page=1' \
  --header 'Accept: application/json' \
  --header 'Api-Key: <redacted>' \
  --header 'Api-Username: rafflebot'
  
curl --request GET \

  --header 'Accept: application/json' \
