Caution: potentially malicious links created by third parties. This is a link-shortening service that can be used by anyone, including criminals who may favor it due to lack of monitoring. It offers a simple abuse reporting feature and it halts bad links promptly when reported; but it should make a lot more effort to self-monitor. Always use a link-expansion service - such as ***** or ***** - to verify the final landing page *before* you click any short-link created at any such service.

This site is just what it says "URL shortened." It is a good site but people can use it to spam you. It is a good site if you use it right. If a random person gives you a link that you do not know then do not click on it. But if say your friend gives you a shortened link it will be fine. If you use this site right it is a good site.

It's a website that does exactly what is says. It's a URL shortener. If anyone wants to scam others with it, you can always click "Report Abuse" on their homepage. This is as good a URL shortener as any other like "goo.gl" or "bit.ly" or even "adf.ly"
