If you publish content on the web, you should always use original URLs.
Link shortening or safety/surveillance services are all very well, but redirects may not work for everyone:
• The URLs are too long for some older browsers to handle
• They are not human-readable, so hide the ultimate destination
• The provider may withdraw the service at any time
That's why I made this.

Microsoft loves you and wants to protect you. So every time you receive an email with a link in it, Microsoft Outlook helpfully rewrites it so that it goes through their "safelinks" system. Safelinks allow your administrator, or someone at Microsoft, to stop you visiting a link which is malicious or suspicious. Rather than going to example.com, your link now goes to safelinks.protection.outlook.com/?url=example.com. Hurrah! If you accidentally click on a naughty link you won't cause chaos…
Just out of curiosity: does anyone know how trackable M365 "safelinks" are?
By "safelinks" I mean the re-writing of URLs in emails by a link into Microsoft's security scanner. The link is very very long and, I suspect, can be traced back to the individual user clicking on the link.
I assume they do this so that they can find out who's email contains spam / phishing /etc. but, at the same time, if the link is safe they know who clicked on what, when…
Seems "wrong" from a privacy perspective.
