UsersWP Restrict User Signups

Open registration invites spam accounts, offensive usernames and throwaway email addresses. UsersWP Restrict User Signups gives you a gatekeeper for the signup form. You set the rules once, and the add-on checks each new registration against them. That means less time spent deleting fake accounts by hand and a cleaner member list.

The add-on can block full or partial username matches, stop signups from known disposable email domains, and accept only the domains you name. A site for a company or a university can limit signups to its own email domain. A public community can block unwanted usernames and addresses. The settings sit in the WordPress dashboard and work alongside UsersWP.

Features

• Full and partial username blocking: Block usernames that match a restricted word exactly or contain it, so offensive or suspicious names are stopped before the account is created.
• No spaces in usernames: Turn on an option that disallows spaces in usernames, which keeps username formats clean and consistent across your member accounts.
• Disposable email domain blocking: The add-on comes pre-loaded with a large database of disposable and spam-related email domains, so you do not have to build the list yourself.
• Custom email domain blacklist: Add your own blocked email domains to the built-in list, so the restrictions match the kind of spam your site actually receives.
• Allowed domains only mode: Limit registration to people who use specific email domains. This suits companies, organizations and schools that want signups from their own addresses only.
• Independent restriction settings: Enable or disable username restrictions and email domain restrictions separately, so you can use only the rules your site needs.
• Subdomain restriction: Domain restrictions also apply to subdomains, so a blocked domain is not bypassed by registering with an address on one of its subdomains.
• Dashboard controls for UsersWP: Manage all signup rules from simple settings in the WordPress dashboard. The add-on is built to work with the UsersWP plugin.
