Yt does do it. In addition, the channel owner has the ability to enable it on purpose.
I've looked at my homepage as I've been a creator and did not find any settings that relate to comment deletion due to included links -- does anyone know where these controls are and how to access them?

See the post above by rjsouza. I havents tried it myself but a couple creators told me that my posts with link ended up in their spam folders, so I guess that is how you enable.
Not sure if that will allow external links to be collected there, or if they get deleted directly by yt, leaving only yt links available for publication.
Edit: the number of "s" in my posts are always correct. They are just scattered in random places.
