CAPTCHA experience?

Hi Thomas,
first, I am assuming you are using WP Pagination and you are using the Save Results Light addon?

Your issue is that bots are following the links for the next page, which once the end of the quiz is reached, triggers the results to save – but since they are bots, the results are skewed? I’m basing the rest of the response off of the above.

So first, there is no way to stop bots from simply following a link on a page without adversely affecting your users, and differentiating a bot from a normal human gets harder by the day.

If this were to happen to me, I’d take the following steps.

Use Cloudflare.

I’m sure you’ve seen their service in action before. You go to a website, but before the website loads, you get a page from Cloudflare stating that they are checking to see if you seem human before allowing access to the main site.

Use a security plugin such as Defender Security

Defender is a free WordPress plugin and has some great tools for detecting and blocking “suspicious” activity, including checking for known footprints of bots.

Use of both of these systems will not 100% guarantee that bots cannot use your site, but they should significantly reduce the chances that bots make it through (and improve the security of your site overall).

Don’t use WP Pagination

There is a reason why the feature states “It is recommended to use the “paginate” option on each question instead.” and why the Documentation Page states “Don’t use this.” (although mostly as a joke)

HD Quiz has a TON of security and anti-spam measures baked right in. Some users literally use HD Quiz AS a CAPTCHA. But the WP Pagination featured requires links in order to go to the next page which search engines and bots can use.
