Which rule are you referring to? The poster I responded to said "The purpose of these meetings would be strictly exercise". So no lessons, no practice of certain steps, just moving quickly around the floor to get the heartbeat up. Sounds boring to me. No mention of art or anything else. There is no rule, Connie can dance for whatever reason she wants, however "strictly exercise" is the last reason why someone should dance, in my opinion. If you taught for a decade, I'm sure you offered dance classes not exercise classes. As for me, I have no expertise, I started dancing in my 40's and have progressed to be a competent International style silver level competitor. I have just come from a coaching session with an amateur champion where we worked on my position and head placement. Not exercise but I wouldn't trade that hour for anything in the world.
