Frequently Asked Questions

Common questions about Stop Signup Spam

No. I am not affiliated with Stop Forum Spam. You can request removal on their Removal Request page.
No. Since the plugin has a very specific purpose, and I would like to keep setup as seamless as possible, it would be best if you deactivated the plugin if you wanted to temporarily disable it.
Please understand that this is a free plugin, which I built out of necessity because spammers were flooding my RCP-powered membership site with bogus registrations. I do not have time to integrate with every membership plugin under the sun. With that said, I am not opposed to pull requests if you would like to contribute an integration of your own.
At this time, all this plugin does is check the registration email address and IP against the Stop Forum Spam database. If either the email address or the IP address appear to be spam according to Stop Forum Spam, this plugin will not allow registration. If Stop Forum Spam reports a false negative, feel free to report it to them so they can have a more accurate database.
As I discover new, accessible ways to thwart signup spam, I may amend this plugin to reflect those. In the meantime, if you have any ideas, I am not opposed to pull requests.
No. It is probably best you block this traffic at the DNS level anyway. Services that provide web application firewalls, such as Cloudflare and Sucuri, may be able to help.
Stop Forum Spam is a third-party service that maintains a database of spam reports. Stop Signup Spam is a WordPress plugin that integrates with that service.
