To test McAfee’s URL shortening service, I decided to try to fool it. I first shortened a URL using bit.ly, and then tried to shorten that bit.ly URL using Mcafee. As expected, I got a message that I cannot shorten URLs that are already shortened by another URL shortening service.
I still decided to push it further. So, I shortened a URL this time with j.mp, instead of bit.ly (j.mp is just another incarnation of bit.ly, but not very popular). Surprisingly, Mcafee did let me shorten that URL! This is not what I expected (or wanted).
However, I think this is just because Mcafee’s URL shortening service is so new, and they might be still working on adding features. I hope they put some sort of automatic check to see if the URL is being redirected somewhere else, and prevent shortening that further.
Nevertheless, this is a first big step towards getting rid of all those spamsters that push unwanted and malicious links via URL shorteners. Thank Mcafee!
