URLs shorteners are used to simplify a complicated URL, for the purpose of sharing.
Shrink it to better fit into Tweets, Instagrams, make it more manageable. For example:
It’s a blind click, just trusting that the URL
goes to where you’re expecting it to
Phishing and social media scams use shortened URLs… example: a private message is sent, “Click here to see the photo I posted of you on Facebook!”.
Click the shortened link > hey this isn’t Facebook > it’s a website that just gifted you a virus, or malware.
Expand the URL, “unmask it”. Then, decide if you want to click it.
If your gut makes you pause, listen. Don’t click it.
Infecting your entire system irreparably, can happen with one bad click.
