@MandyMay @beep sort of an art. Basically the URL should appear clean.

This one isn't. Everything after the ? is garbage:

buzzfeed.com/morgansloss1/celebrities-natural-hair-color?utm_source=dynamic&utm_campaign=bfsharecopy

This link is clean.
buzzfeed.com/morgansloss1/celebrities-natural-hair-color

This is if you really want to mess with them:
https://buzzfeed.com/morgansloss1/celebrities-natural-hair-color?utm_source=buzzfeedsucks&utm_campaign=dumbtracker

NOTE: I removed the https://www. frrom the demo URLs otherwise mastodon would render / make clickable

EDIT made the buzzfeedsucks one clickable and broke the clean one for better illustration
