Plugin Description
Tor is an invaluable tool for protecting free-speech, privacy, and preventing surveillance but when abused it can protect the identity of malicious users and make tracking their activities more difficult. “Hackers” might use Tor to run security scans on your website or spam websites with comments and fake registrations.
The purpose of this plugin is to give you the power to block certain Tor activity from your WordPress site.
Features include:
- Block Tor users from registering on your site
- Allow Tor registrations, but flag them for review
- Block logins from Tor (useful for preventing brute force attacks and securing your admin panel)
- Block Tor users from posting comments to your site
- Block spammy pingbacks & trackbacks from Tor IP addresses
- Block Tor users from your entire WordPress site
- Permit access after solving a CAPTCHA (requires hCaptcha for WordPress plugin)
- Real-time blocking using the Tor DNS exit list service
- Near real time blocking using a cached blocklist which can be updated every 10 minutes or more
- Custom blocklist support. Block IP addresses or host networks.
- Statistics to show how many Tor actions have been blocked by this plugin
This plugin is compatible with BuddyPress, the popular Login With Ajax plugin, and hCaptcha.
If there is a feature missing that you would like, request it!
If you opt to use the real-time blocking, each IP address looked up is cached for 5 minutes for efficiency.
The Tor IP lists that are downloaded only contain “exit node” IP addresses so it is relatively small and the list is searched using a binary search so the plugin is very fast!
This plugin also adds two shortcodes which can be used to display specific content to Tor or non-Tor users. Shortcode usage:
[tor_users]Hi, I see you're using Tor. I support privacy and free-speech too! Visitors not using Tor will not see this message.[/tor_users]
[non_tor_users]Defend yourself against tracking and surveillance. Circumvent censorship. Visit torproject.org to learn more. Visitors already using Tor will not see this message.[/non_tor_users]
