Mommy needs to be more vigilant.
Maybe switching around her posting times to various hours of the day and night have thrown her off balance.
A problem with copy-paste of large blocs of text is evident when such a phrase slips in so easily. This suggests that she does not actually read all she posts. Copy-paste can be a fine tool, but also a gaffe maker.
Perhaps her most ardent fans don't actually read all that is posted? Cheering for a team -- think NFL -- is more sports than intellectual rigor.
