Maybe you could add an option “Bot safe voting (requires JavaScript)”.

It would deliver star images with an ID or an HTML5 data-* attribute, which would be transformed dynamically by JavaScript on page load to links with corresponding href.

Thus you could leave the decision if JavaScript should be mandatory for voting to the blog owner. The blog owner could, for example, decide to put a message on the blog like “voting requires JavaScript”.

Ok, I see your point.

Maybe the rating could be ajaxified a little bit more: A lightbox with a captcha could pop up after a user clicks on an image. This would stop bots for sure.

Hi,

I have the same problem (crawlers and bots voting on images) and would recommend to change the way voting works: change the regular http links to small HTTP forms. I suppose there are much less bots and almost no crawlers who use HTTP forms.

You could add honeypot hidden input fields – only bots could fill in values. This behavior could be used with blocking these IPs.

What do you think?

Greetings,
