Custom Referral Spam Blocker gives you the control to ensure that dishonest referral sources are blocked from Google Analytics.

We provide a strong default set of spam referral sources and block them for you. Referrers can quickly be added in moments using the WordPress Dashboard.

At this time, we are unable to block referral spam when used in conjunction with most CDN configurations.

If I customize my list and new default sources are added, will my list be updated?

Future versions are planned with improved support for appending to default versus replacing it with your own list.

What is the correct way to add new domains to the block list?

This plugin blocks requests for all pages from a given domain or subdomain. Each domain should be added on a new line. For example, if you add "imaspammerandimok.com" to the list, requests with referrers such as "http://imaspammerandimok.com/spamallnight/spamallday.html" will also be blocked. Do not include the protocol (https://, http://) or path (/folder/page.html) when adding new domains. Subdomains, however, must currently be entered individually.

What happens to the evil spammers?

Their requests are intentionally blocked from continuing to load any WordPress code and get directed away from your site. If they have a puppy, it cries.
