I added the above code suggested by Sammie in addition to some provided on expertzzz, for anyone, it goes it the root .htaccess file after the rewrite engine on statement, see below:

RewriteCond %{QUERY_STRING} ^http [OR]
RewriteCond %{QUERY_STRING} ^.+www\. [OR]
RewriteCond %{QUERY_STRING} ^.+https [OR]
RewriteCond %{QUERY_STRING} ^ftp
RewriteRule .* - [L,F]
RewriteCond %{HTTP_USER_AGENT} ^libwww [OR]
RewriteCond %{HTTP_USER_AGENT} ^Wget
RewriteRule .* - [F]
