Thread:Extension talk:ConfirmEdit/Possible bypass?

Is it possible to bypass this extension in this manner:
 * 1) The extension allows for a correct solution to be presented then saves this as a cookie, os that people aren't inconvenienced when using multiple tabs/windows. Isn't it possible for someone to manually enter a solution, then just keep spamming the site, possibly (with a non-static IP connection) periodically putting in ipconfig /renew on the command line to get a different IP address?  It seems like the cookie that stays on the computer would allow a person to basically completely bypass this after a single correct answer is given.  I'd like to turn this cookie off, but I'm not sure whether that would break anything else.  I only have this turned on for account creation, I turned this off for edits in my localSettings file.
