While trying to vote for the server today, I experienced difficulty getting the captcha for minestatus.net to load. After several attempts, it finally loaded. But when I clicked vote, the Opticraft page redirected to the main page, with this error message:
This server has been disabled by Minestatus. Reason: Circumventing the vote page on Minestatus, abusing anti-automation challenge to proxy the CAPTCHA onto their website.
Just an FYI, not sure if it can fixed or not. Looks like we may have to go back to the old voting system for that site.
