On most (all?) carriers, you can forward spam SMS messages to 7726 ("spam" on the keypad) to report messages as spam.
That said, I've got no idea if they actually do anything actionable with this data. It certainly doesn't seem to have reduced my spam volume. Now I just let Android Messages filter the spam out.
