Today I noticed several domains are using masking to associate their domain name with my content. E.g. “draughtmark.co.uk” and “recycleofficewaste.co.uk” (plus several others). Can I prevent this and bots from indexing my content under those domains (otherwise my site will get penalised)?
I have since put in some Javascript and a PHP function to detect and redirect to my site. This seems to prevent people from unknowingly browsing my content on another domain, but I don't know if this will help in regards to the bots as it either requires the Referrer to be set or the Javascript file to be loaded.
