[QUESTION] Block Incoming Traffic Through .HTACCESS File

Tried editing a site´s .htaccess file to block any incoming traffic from site´s I believe are potentially spammy, low-quality, and/or toxic.

Unfortunately, the code snippet broke the site, and I don´t know why.

So, I would like to run the code through you guys and see if you spot the error.


# Block Referral Traffic From Spammy Sites
RewriteEngine on
RewriteCond %{HTTP_REFERER} ^https?://([^.]+\.)*domain1\.net [NC,OR]
RewriteCond %{HTTP_REFERER} ^https?://([^.]+\.)*domain2\.info [NC,OR]
RewriteCond %{HTTP_REFERER} ^https?://([^.]+\.)*domain3\.org [NC,OR]
RewriteCond %{HTTP_REFERER} ^https?://([^.]+\.)*domain4\.info [NC,OR]
RewriteCond %{HTTP_REFERER} ^https?://([^.]+\.)*domain5\.org [NC,OR]
RewriteRule .* - [F]

Thoughts?

Getting 403 or other error?

Whoever wrote that for you - they overdid it -https://httpd.apache.org/docs/2.4/rewrite/access.html and try with simple versions and work your way up.

2nd line the same for multiple domains, and make sure the last one matches 3rd.

Loads of info online, try restoring your site to a previous version via cpanel
