I encountered this same bizarre misunderstanding of the rule here:
The poster quoted the portion of the post they were replying to. That is fine. It has always been fine. The meaning was not “radically changed”. Moderators should know better. While a mod’s new and unique misunderstanding of the rule is fixable, an understanding of English writing that brings one to write the following may not be:
What you did is extremely misleading and putting a different meaning to what another poster said.
If you don’t think pulling that one sentence out of that long post change the context, there is nothing left to be said. To me it was very blatant.
I will go on record to say I did not agree, but did agree that if they felt I should rescind it, I would.
