We have an issue where spammers are subscribing to all our feeds. I already disabled all feeds via a function, as well as using a plugin.
Each day they still appear in our logs with thousands of entries. For example:
/leaderboard/feed/index.php
/leaderboard/feed/
/some-category/feed/
Is there any way to block access to all visitors querying /feed/ or anything containing the word "feed" in the URL via .htaccess, and deny them access to the site?
