Anti-spam NOT

This morning I received an automated email from "0Spam". Here is the text:

IF this is genuine , then this has to be the dumbest method of implementing anti-spam I have encountered. A simple search of the intewebnettubes shows that I am not the only one who considers this rather dubious. How effective is an anti-spam system if it generates an email for every 'dodgy' piece of email? It would simply make web traffic matters worse. If you are using this software then your 'netiquette' is very low. You are passing the responsibility of checking an email as being valid back to any genuine user and increasing overall net traffic.

Yeh! I am really going to click on the link (I've chopped it out but it contained a longer user-id string.) to advise the user. IF it were genuine it should have included a proper subject matter and should have identified the recipient in a better way. There is no way I would click on the link 'blindly'. Additionally, one of the principles of an effective approach to spam is to not respond to the email sent and simply deleting the email. Responding just identifies the address as an active account.

A simple search of the interwebnettubes shows that I am ont the only person with this view.

Should you be someone who is blinded by their logo that claims "A Virtually 100% effective Free Anti-Spam Service" then you are certainly not getting all of your emails as people are going to go "Hmm. Looks rather dodgy to me" as they click the 'Delete' button or, as I did, simply marked it as spam
