Generally when you are going to take a full URL and tinker with it, you want to make it shorter. Given that demand, there are more URL shorteners than we could ever use.
Thankfully, people have not left overdone alone, and have made something that will not make your URL shorter, nor more useful. No, instead that concocted ShadyURL.com to make your URL lengthy, and well, shady.
Take for example a very vanilla link, say to this. Feed the full URL into ShadyURL and what do you get?
Go ahead, try it. See? Now of course, these prank URLs can be used in any number of nefariously polite circumstances, or not. Just a word of warning, given that the company calls itself shady, no promises that they might not just repoint a few links on a special day just for fun.
Finally, we must give the website a thumbs up for their tagline: Don’t just shorten your URL, make it suspicious and frightening. Enjoy, everyone.
