Mr 80:
I’m not sure. Chumra Creep is a real issue, and perhaps this was a humorous way of trying to get the point out.
I’ll add to the list:
One must wear a black hat in the street
Girls must walk in pairs ONLY
No family pictures in your home (Tznius!)
(I’m not talking about pictures where the couple is touching, which should not be done in public anyway).
Shidduchim must only be made by a registered Shaddchan from the Yated Shidduch Forum.
Not cheating on taxes or to get benefits
(strike the last one, that might be real).
