Polls: Prevent the same IP to vote more than once !?

[wii]

I only have one serious technical problem with my board.

Polls, people who know how, just delete their cookies and vote again, so often I have someone (don´t know who), who votes hundreds of times on the result he/she wants, and therefore ruin it for everyone else.

Is there a way to prevent the same IP to vote more than once?

[wii]

Anyone interested ?

I'm pretty sure a member cannot vote twice in a poll, unrelated to what cookies they may have set.

I have guest polls, and would like a guest to only be able to vote once per IP and cookie. Now if they delete their cookie, they can vote again.

[wii]

I´m still interested in this, if anyone have an idea on how ?

You didn't specified which system do you use for polls, but vBulletin doesn't allow to an user vote twice in the same Polls...
You can always go to the 'Paid Request' Section and you may receive your answer

System ? Just the built in poll system of vBulletin, guests can vote over and over again if they delete their cookies, this is what I would like to avoid by adding IP check to the polls, so that it would be much harder to cheat.

Yes, this is a problem when opening polls to guests. Opening polls to guests allows you to get many more votes than to not do so. But guests will just keep voting if the poll is important to them. An IP check would be optimal. It would not hurt to suggest this function on vb.com.
