WRONG. SS a mod for 6 years clearly stated that breaking local rules will mean your posts get deleted.
Excuse me, but where is that stated? I see only this:
26. Local thread rules, if stated properly when the thread was started, specific enough and don't conflict with the forum rules, have to be followed.
There is nothing mentioned in forum rules that someone can forbid users to post on-topic replies in threads they started.
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.
She was probably ranting and spamming her off topic replies.
