There are 2 problems I see with this kind of link:

1.) A user doesn't see where the link takes him before he has clicked on
the link, so he can easily be taken to a "bad" web site.

Bitly has a feature to preview the link destination.
For example, for http://bit.ly/2hGKTgX add a plus character 
http://bit.ly/2hGKTgX+


You get this information with the + version of the link:

Cyberattacks on GPS leave ships sailing in dangerous waters – Naked Security
https://nakedsecurity.sophos.com/2017/08/07/cyberattacks-on-gps-leave-ships-sailing-in-dangerous-waters

bitly.com/2hGKTgX


Info copied from Bit.ly web site FAQ.

 There were some "preview shortened link" sites, but you'd have to 
trust one of those to use that approach.


When I have a link like this I wish to expand, I use linux command line 
/ curses browser lynx.  No way to infect anything with it, and view all 
the indirections as they pop up.


I agree, I seldom bother with the current malware / security 
environment, better to do that than risk it.  And I always tell anyone 
who asks me for advise as you do, skip it, unless you really know what 
you are doing, or you will get pawned.


thanks

2.) These short links eventually expire after some time, so if you find
an email with the short link later in the ML archive then the short link
may not work anymore, even though the original link may still be valid.

There are dozens of URL shortening tools that can be used via a web page.

Try this instead:

Often when you see a long URL, or one full of strange numbers, it's encoded or 
encrypted personal tracking information. In this and many cases it's safe to 
delete everything that's part of the utm_source= keyword [1] and try again 
before you cut/paste the URL into a posting for time-nuts. Not only does it 
make the URL short and readable, but it also prevents your personal tracking 
information from being leaked to the mailing list and permanently to the web.
