While most of these fraudsters are lazy and send their requests in emails, we the odd time still see a physical snailmail spamletter coming through our letterbox.
Today I reveived an old fasioned letter from someone titulating themselves as "Domain Renewal Group" with a logo looking like the US flag (Probably to make it more official looking) warning me that one of my domains are about to expire. Up in the right hand corner of the letter they had the scary title "Domain Name Expiration Notice".
If you happen to get one of these letters, then simply throw this in the bin as it is a scam!!
