Prevent registration and subsequent spam on your WordPress blog by preventing registration from blacklisted domains and email addresses. Although I am not sure that requiring registration for comments is such a hot idea, this plugin might be useful for those that have set that flag but are still facing spam problems or bogus registrations.
Installation and usage:
- Download Registration Blacklist plugin and extract to a local folder.
- Upload extracted file to wp-content/plugins/ folder.
- Activate from the plugins page in WordPress Admin panel.
- Go to Options / Registration Blacklist. Selecting this will show a text box. Simply add domains or full email addresses that host email accounts that you don’t want to be used to register a user account.
