Strange domain redirecting to my site

[strunch]

There is a strange domain that is redirecting to my business site. I don't know the purpose of this but I don't like it...google is indexing my content and associating it with this fake domain. Is there a htaccess rule I can use to redirect these incoming requests? Also, why would anyone do this? Is this a competitor trying to damage my rankings? Thanks for any help?

Tried this but not working

RewriteEngine on
# Options +FollowSymlinks
RewriteCond %{HTTP_REFERER} badsite\.com [NC]
RewriteRule .* - [F]

Both my site and this strange domain are using cloudflare.

Ok, I see a lot of user agent strings in my log file with this bad domain, some from search engine crawlers and many from site uptime checks. I hope to block these requests by using this:

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_REFERER} ^http://(www\.)?.*(-|.)?baddomain(-|.).*$ [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ^.*(baddomain).* [NC]
RewriteRule ^(.*)$ - [F,L]
</IfModule>

But I still don't understand, if i type this bad domain in my browsers address bar it still points to my site. Why aren't my htaccess rules stopping this? I feel this bad domain does not have a host, they simply are using free cloudflare to redirect their domain to my site. I suppose I could block cloudflare but I don't want to do this since I am using it myself. Any thoughts would be appreciated. Thanks.

Have you contacted cloudflare and complained?

[strunch]

Yes, I wrote them yesterday and am awaiting a reply. I also contacted the bad domains name registrar.

Well they would have the solution. Normal regex blocking methods not working may be related to cloudflare's routing schema.

Cloudflare just told me that they aren't a hosting company and that I should focus on the ip address that the bad domain resolves to, which is me. So essentially they told me to block myself. I guess I am powerless against this attack. Hopefully it won't cause my domain too much damage. Perhaps if i knew the true ip of the bad domain it would help, but when i look it up, it lists my domain ip and since it is using cloudflare i cannot see this domains true ip address......*confused*

Ok issue resolved. Received another response after I explained more clearly what was happening.
