Selective blocking of trackbacks, pingbacks
Easy to translate
Compatible with caching plugins
Purposely no obscuring techniques so that the anti-spam word is easy to read

Unzip all files to the folder custom-anti-spam in your plugins directory, so that the path is wp-content/plugins/custom-anti-spam/. Then activate the plugin via your WordPress admin section. The plugin should work directly “out of the box”, but all settings can be customized in the Settings > Custom anti-spam page in your WordPress control panel. If you are upgrading from a previous release, de-activate that release first.
Please visit the plugin page at https://www.theblog.ca/anti-spam with any questions.
