My most relevant experience: A colleague sent me a paypal link that allows me to accept money. Nowadays, I know that it was legit. But instead of paypal.com, it was something like py.pl?code=abcdef or p.pl?code=abcdef or whatever… Thanks, Paypal!!. Clicking the shortened hyperlink did not save me any time, but it wasted multiple minutes for me to research whether the domain was a scam or not.
