Looking at the show list, I see no-one does that. Perhaps it's not possible if you don't own the server (e.g. you share a GitHub repo), but if not then I don't understand why people don't do that. I understand that some simply don't know about UTM, but as most people in here are tech-oriented, I think that number should be small. There are perhaps some other reasons, like: - The effort of adding the parameters manually (even via link builders) outweighs the benefit - Their main sharing platforms have built-in traffic tracking methods. If they don't run a lots of channels they could just be using a more singular channel pixel or conversions API to provide measurement. If you only have one source of traffic then UTM parameters may be overkill
I still don't see how most people in here have these problems, but perhaps I'm wrong.
Note that if you have your own set of params or use a link shortener to hide them, then I still count as using UTM. I also have an elaborated question of this in [Webmaster Stack Exchange](https://webmasters.stackexchange.com/q/144604/52079).
