Sometimes they have IIRC.
Or ignore the men who post. That's always an option.
You ladies know better than I if this works with most men but my guess is it does. Unless there's an official ruling, I would have OP put in their post how they only want responses from ladies. If a man responds multiple times (vs an accidental one-off), I'd report him, so mods can ask if he's going for the princess crown at the tea party.
