Internet spammers commonly use abbreviated or hidden URLs in an effort to get you to click on a dirty URL that is most often linked to porn or a downloaded virus.
A great way to uncover the truth behind a potential spammer’s dirty URL is to use www.LongURL.org
This website is free and easy to use. Just go to www.LongURL.org and copy and paste the questionable URL into their interface. This will then expand, or uncover the true URL.
This is great especially in the case of email spam where readers are often tricked into clicking on phony URLs. This site has a lot of great support behind it including the NY Times, Washington Post and PC World. I definitely recommend adding this website to your ‘favorites’. Use it often to protect yourself and your computer.
