All URL shorteners have the problem of not being transparent with
destination. The risk of this is amplified on places like Twitter,
where the shortened version can be copied and pasted numerous times.
A common trick for tracking who opens your links is to use a URL
shortener in conjunction with a tracking script on your own server.
The extra process is likely to go unnoticed by the person clicking it
(and even if, it's too late). That can launch virtually anything
before sending the visitor on to the destination.
eg: bit.ly/RZDLHg > domain.com/go/netflix.php >
Some spammers also use multiple shorteners to try to hide the destination.
Less well-known is using base-64 to include code in the url itself:
So I would recommend using a site like unshorten.it (or bit.ly itself)
to actually see where a link leads.
