I don't think that is technically true. The purpose of the ignore/block is not to prevent someone from posting to the ignoree/blockee's posts. It is simply to prevent you from seeing THEIR posts.
But in the case of lets just say themickey, (God help him), he can have me on ignore/block and post BS posts to me and about me in a thread that I start, but I can't see his posts or return fire to his abusive posts. wtf this cannot be the purpose of ignore/block. No way Jose.
