Custom field value against votebots

    Hi there!

    Occasionally I have votebots attacking my poll, inserting insane amounts of votes into database. I use blocking votes with cookies option and captcha. Still, I have many spam votes daily, usually with same IP’s. Manual deletion of extra votes is time consuming and annoying.

    I don’t wont to block IP’s manually or otherwise…

    I was thinking… Could I use custom field value as a security measure? Something similar to captcha. For custom field question i could ask a voter to add two simple numbers or write some specific string as an answer to some specific question and check the input, and if input isn’t valid or the answer is false, the error message “Your answer is false” pops in and stop script from registering the vote.

    Where in code could I check for custom field value input and validate it so that vote wouldn’t be inserted if that field input is false?

    Thanks in advance,
    Merkuriel

    Hello

    Even if you’re using captcha, you’re still getting spam votes?

    Please let us know.

    Yes. I even deactivated captcha and wrote some custom code for random string generator as a custom textual captcha with hidden fields, and still I get spam votes. The poll options are set for min/max 3 answers per user. I get like hundred identical IPs with message=Success in Logs table in database. Do bots somehow access $_POST method directly with skipping the submit button validations?

    Thanks,
