If your block bad query plugin uses htaccess code then you would copy that htaccess code into this BPS Root Custom Code text box: 14. CUSTOM CODE BOTTOM HOTLINKING/FORBID COMMENT SPAMMERS/BLOCK BOTS/BLOCK IP/REDIRECT CODE, click the Save Root Custom Code button and activate Root folder BulletProof Mode. Doing these steps will combine your block bad query plugin’s htaccess code with the BPS htaccess code in your Root htaccess file.
