This URL shortening site is used by many spam and scam artists.
I find so many youtube online streaming scam operations using this site!
This site does have a reporting link directly on their main site, which does not seem to work very well.
This is a smart URL Shortener.
It's just like any other URL Shortener in the globe (goo.gl, etc) they get abused from time to time.. but it doesn't mean the website itself is bad.
V.HT provides solid and great URL shortening service.. +++
