You want to access your WordPress admin panel, or you are using it already, but suddenly you get a message (in an overlay maybe) telling you “your ip is on a spam blacklist“.

This is caused by a plugin in your WordPress site, and the plugin could have been installed by you, your host, or a 3rd party WordPress installer. Using FTP or host’s file manager, rename the plugin directory in wp-content/plugins to solve the problem. Alternatively you can try to remove your IP from spam blacklist here. Ironically you may not be able to reach Stop Forum Spam website from your blocked IP!
