Just out of curiosity I searched for UTM parameters with source:*?utm_, looks like there are about 1500 posts with this kind of tracking parameters. I wonder if any effort should be made to remove these tracking parameters?
Topic: utm_source tracking parameters in source URLs

Looking through some of those posts, I can see that the biggest offenders are from Patreon, Reddit, and Instagram. Plus one from TikTok. The origin of the UTMs come from the uploaders clicking the share button on the source's web page instead of copying the URL from the address bar. To remove them, someone would have to make a bot, unless they want to manually work through all 1500 of them.
To any bot makers out there, the Regex expression utm_\w+=\w+&? could be used to remove the UTMs while preserving any other parameters.
