@ metguru:

Because it's not truly anonymous, considering your username and vote are saved in the database so you don't vote multiple times.
That is an interesting question, as I haven't adjusted a poll since the hacked version of vBulletin, other than when asked to correct typos or change wording. IIRC what happened was someone wanted an option added to a single choice poll and then someone else wanted their vote changing to it. I am pretty sure that it let me make an addition, but didn't ask me for a compensating adjustment, which I thought was odd at the time.

If this is still the case with our current version of vB then it suggests that the way you vote isn't recorded, and that the total number of votes isn't compared with the number of voters. Otherwise the values would return to their originals every time the database refreshed, or the admins/mods would have to be able to alter individual votes and not the totals.

Anyway, this poll is flawed, as it only has a "yes" or "no" option. There should also be an "I don't know, I'm in The Cloud" option as well
