I’d like to ask because I’m curious how secure my votes are.
I asked the same question one tine. As I recall, a Mod said maybe – a BIG maybe – they could if they could figure out how to do it but that it was doubtful.
Of course, they would say that, wouldn’t they? 
I am a mod on a different forum that also uses vBulletin. It’s a different version of vBulletin, and a lot of the options are set differently. But fwiw, mods cannot see how a poster voted on an anonymous poll on that board.
(Mods can change both the wording of the questions and the number of votes, though. I’ve never done it, so I don’t know if there’s any indication they have been edited.)
At least as secure as in the most elections? 
I have edited polls to correct errors. There is no indication on the thread or the poll that it was edited. I always add a note in a post to the thread indicating what was done.
Similarly, if we edit the thread title or sticky/unsticky a thread, there is no indication of that either.
I can edit anything in the poll and can edit the number totals, though I can’t think of any reason why I would ever edit the poll totals. I’m very reluctant to change anything in a poll that might alter its outcome, so I consider anything other than an obvious typo or error to be off-limits, even though I have the capability of editing much more than that.
While nothing is visible to regular users, admins and other mods can see what changes we have made. There is also a field on the edit screen where we can leave notes or an explanation, though usually whatever we are editing is obvious enough that we don’t need to bother filling it in. If anything we do is ever questioned (poll-related or otherwise), we need to be able to justify what we did and why we did it.
If there is a way for moderators to view who voted for what in an anonymous poll, I am not aware of it. I also can’t come up with a good reason why I would care to view that information even if it were available to me.
Question answered. Thank you.
I’ve never understood the concern people here have about voting in public polls. I’d get it for a vote like “have you ever been the victim of sexual assault?” Or similar, but the vast majority of threads here are something like “Pizza: cheese or pepperoni?” Yet I’ve seen people in threads like that complaining about the poll being public. Who cares?
The majority of polls are indeed generic and mundane, however occasionally one comes up where it might be embarrassing for people to know how one has voted.
I was just curious if voting in such a poll was visible to mods or Tuba, I guess.
I mean I’d probably stay entirely away from polls like “Have you ever inserted a butt plug?” or such.
I haven’t, BTW. 
For me, it’s just policy. I don’t vote in public polls, period, regardless of how mundane they may be. Maybe I’ll change my mind in the future, or maybe I ticked the wrong choice accidentally. Best just to avoid the whole thing.
Rather like a notice I saw on a bulletin board way back in the days of stone skins and bear knives: Why, yes, as an Admin I can read your stuff, but I’m not that bored.
In another voting system I have found, accidentally, that I could temporally remove a poster and find how it effects the poles, then replace them this was done to remove a embarrassing typo, it was better to remove it ASAP, then correct it. There would be no notification, however if someone checked at that moment they would see that posting removed.
Just curious, who did you get to do it then? 
Why avoid such a poll if you have, er, nothing to hide? 
But… why? If you changed your mind about cheese vs pepperoni or whatever or if you accidentally checked the wrong box – who cares?
Ah well, agree to disagree I guess. Maybe I should post a poll asking whether you’d vote in a public poll or not 
I’m not trying to change your mind and get you to vote in public OR private polls. I rarely vote in either. But I just don’t get this particular reason to avoid public polls, but it seems to be a very common one.
If you were a veteran of the New York/Chicago Pizza War you might feel differently.
In general, I don’t vote in public polls because there is usually no reason for them to be public. So I wonder why the OP chose to make it public - what info are they trying to gather on posters? Maybe the OP is a PETA militant and is going to come after all the pepperoni voters.
I’ll join the mod chorus and say that I just fooled around with it a bit and haven’t found a way to view a private poll voter’s record. I’d bet it’s less a matter of ‘privacy must be protected’ than the developers not giving a damn about putting the functionality in.
And I’ll also join the ‘don’t know, don’t care’ cadre about posters voting on polls. It’s your problem and vote, not mine.
Hmm, interesting point. The board I moderate allows posters to have multiple accounts, so it’s pretty common to make polling public to avoid “alt bombing”. I suppose that’s not a significant concern in this board.
Still, I find it interesting to see whether liberals or conservatives favor candidate X, or think the VA governor should step down. And whether it’s Americans who like some food, or… In general, I’m often interested in who voted how in a poll.
That’s really a thing you worry about?
