Today, I received an email from a marketing agency enquiring about advertising opportunities on my website. The confusing thing was that the website domain mentioned in the email isn’t owned by me!

It appears that some idiot has set their domain DNS records to point to my website! The “mystery” domain in question sounds very asian smut orientated. Here is what I found by digging further:-

The “mystery” domain has only been registered recently.
It has already acquired the same Google Page Ranking (PR) as my own website with a 7 year old domain name!
