Double Vote

    Great Plugin!
    I’m having a random issue. Every 3-4th vote when the user clicks the vote up or vote down, it causes a vote for both sides.

    I have tried to check other plugins for any conflicts to see if I can isolate the issue. But not joy.

    Have you ever seen this before? Any idea what might cause this behavior?

    Thanks for any help.

    I think it might of been a BOT attack.
    We received over 2500 votes in an hour period from one IP. So when real people were voting they were just seeing the other votes update once they submitted.

    Know of any way to implement re-captcha on the vote buttons?
    For human verification.

    Wow, I haven’t had feedback on similar cases. Specially the bot attack.

    Theoretically it should be somewhat protected, the script can’t be called directly. Perhaps that isn’t enough.

    I don’t know how you would add a captcha there, I’m guessing you need to do extra checks before calling the ajax function.

    If you happen to have a solution for the implementation, please let us know.

    Thanks Ricard,
    That is good to know that the script can’t be called directly. That is exactly what I figured happened. Could of been a person sitting their clearing their cookies or not allowing cookies and just reloading the page. Once I blocked the IP it stopped immediately, and never saw the double vote issue happen again.

    BTW, know of any way to set it up to only allow 1 vote per IP address? Might need to make it server side stored, vs. Local Storage? Which kind of kills the low overhead, which is what I enjoy most about this plugin.

    I’ll let you know if I find other solutions for securing it.
    Thanks for your info.

    Yeah, sure, I guess you could set your browser to not store anything and keep voting. Although doing 2000 votes manually sounds exhausting! ??

    Regarding the 1 vote per IP. Yes, you would need to store that in the database I’m afraid. I believe there are plugins out there that already have this feature.

    Regards
