Stop Signup Spam
Stop Signup Spam will prevent user registration of anyone trying to sign up with an the email address or IP address that has been reported to Stop Forum Spam. Contrary to what the name implies, Stop Forum Spam can be used with any web service, not just forums. At this time, Stop Signup Spam integrates with: The core WordPress registration form Restrict Content Pro MemberPress Give By installing this plugin, you consent to an API call sent from your WordPress site to Stop Forum Spam after every attempted user registration. The API call includes the user’s email address and IP address. It is a similar concept to Akismet, except instead of checking for blog comment spam, it checks for user signup spam. Unlike Akismet, no API key is required to query Stop Forum Spam’s database. Partly because of this, I decided not to include a settings page in the Stop Signup Spam plugin. Just activate and you are all set. The plugin does not log any user registration info. Any data sent to Stop Forum Spam would fall under their privacy policy. Please note that Stop Forum Spam is a third-party service that I have no affiliation with. I just found it, could not find any existing WordPress plugins that worked with it, and built one myself. It has helped me cut down on signup spam on a free membership site that I run, and I hope it will help you do the same.
VigilanTor
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] Support Tor Tor is a great thing.
