This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Tor Blocker


FIX: Google crawlers aren’t blocked any more.

IMPORTANT: Development of this PoC plugin is over ( there are performance and security issues with it ). Please use instead!

IMPORTANT: On update always deactivate plugin, update the code then activate again e.g. all plugin settings will be lost. This will be the case until we add all of the planned features and when we turn to UI/UX development this won’t be the case.

Most of the time Tor exit nodes and another .onion web proxies are used to enumerate vulnerabilities of our online product, to perform attack or to be used as a spam source.
This plugin allow us to limit the actions that coud be performed by the users that are coming from a Tor nodes using free service.
Could be upgraded to premium (from September) or could be set up any url to service that will give you response in the described json format.
Premium list is updated on real time, free on 10 minutes and has its own caching mechanism so isn’t affect the speed of the WP instance.
In case you need the realtime Tor blocking service feel free to contact us at contact [at] hqpeak [d0t] com

With this plugin you can apply following constraints to the Tor visitors:

  • Filter human from bots visits from Tor network
  • Visits (Tor users can read only public content on the site)
  • Comments (Tor users can post comments)
  • Registration (Tor users can register for the site)
  • Subscription (Tor users can subscribe)
  • Administration (Tor users can access administration panel)
  • Request (Tor users can send POST requests)

Or to ban any action by its name / key e.g. not allow accessing resources defined by some GET or POST key.
Un checking all of the boxes will block all of the requests to your wordpress.

Update: Now you can show user friendly message to the Tor visitor and/or you can
log all of their actions.

Update: Captcha challenge for stoping bot scripts and fallback service solution.

Update: Country based GeoIP blocking and user friendly customizable block page.

Update: ASN number based ip range blocking. Adding ASN you can block any hosting/cloud provider automated requests. Every cloud/hosting provider as Amazon. DigitalOcean, Hetzner,… have their own ASN.

Update: Security update – XSS, DB tables column types update

What if I have problems activating the plugin?

For any problem you face with the plugin activation, please visit support forums or contact us at

Does this plugin work with newest version of WordPress and also with older versions?

Yes, this plugin works really fine with WordPress 3.8.1!
It should also work with earlier versions, but the testing was done at the latest stable version and that is 3.8.1,
so you always should run the latest WordPress version to escape possible problems.

What if a user using tor is not in the list and happens to come to the site?

No worries. The tor exit list is updated frequently each 5 minutes or 5 hours, depending on which version is used,
so users using tor that are not on the list will be updated after this amount of time and thus will be denied by the plugin.

Do I have to set up the settings every time I activate the plugin?

Yes. Every time the plugin is activated its options are set to default values, so it means you have to set them up again.

How many request parameters can I put in the textarea to limit the user by request?

No limit at all. You can put as many parameters in the textarea as you want. The plugin will recognize any request parameter in the URL
and stop the user immediately.

What is allowed to the tor users by default?

By default, tor users are allowed just to visit the site and read its public content. As you might guess, you can deny this too,
so the tor user is stopped before reaching your site.
