Jan has been posting there under Digger's account (see her past updates).
Those 3 posts stood out for me as an attempt to create the illusion of a "nameless backer" defending the producers. I think it backfired when she realized after posting that she was actually posting as Digger (duh). And to "fix" that, she adds "This is a message that was sent to me and I am posting here for the backer as requested..."
Ask yourselves, why would a backer need Jan or Digger to post messages on his or her behalf?
If that backer really existed and wanted to come to their defense, he or she would have posted directly. No need to send to Jan (who doesn't have a KS account herself) to do it.
