Yes, but theymos also said:
OPs do not own the replies to their topics, and unless it is self-moderated, they have no right to have the replies deleted.
When in doubt I would look to more recent statements made by theymos. I honestly have completely disregarded it when I see the "local rule" though they are usually pointed to someone else. I say post away, let the Mods decide. This is a public forum and I don't see theymos encouraging these "rules", when there is an option available.
To bad for them if they forgot to make it self-modded, they can take their ball and go home.
WRONG. SS a mod for 6 years clearly stated that breaking local rules will mean your posts get deleted.
Tman an authority on this forum I believe also stated that local rules if broken will result in your posts being deleted. He successfully used local rules to remove cryptohunters posts which he had banned in the local rules. LoyceV the robovac AI here also started the local rules gold rush.
Steamtyme does not understand there is no self moderated "option" available in meta. It seems unlikely someone would forget to make it self moderated while typing out local rules
well, there are some here in meta who clearly could get that confused.
