URL shorteners were made to make sharing website links a whole lot easier. URL shorteners are very convenient but come with a risk. When clicking a shortened link, you have no idea where it can send you. From a security perspective this is unacceptable, the risk is too great.
Instead of blindly clicking a shortened URL and hoping for the best use http://www.unshorten.it/. Unshorten It removes the risk of the unknown and guarantees your security. Just drop a shorten URL into the bar and Unshorten It handles the rest.
