It appears that one of my polls on http://www.zeroculture.org is getting hit by a bot or some similar type of script. One particular option in the poll gets voted up much higher than any other option (this is above and beyond normal usage for my site). The timestamps on the votes are all withing a few minutes of one another, yet they all come from different IPs in different ranges. Short of disabling polls for unregistered users, is there any way to prevent this?

Thanks,
Mark

May be you can disalow access to the module's dir in the file robots.txt ???
