Well, for whatever reason, DPC decided to make that an optional call for those on the M&J route, so whilst they could and probably should have called him no matter what, this is how it is.
Also, I've had people text saying things like, "Call me when you get this", instead of just phoning, so them doing this isn't unusual.
Another for the overly-punitive ban club.
That sucks man. DPC really is very unforgiving and quick to judge people, but what's the full story here? What were you asking for and why?
Also, this YT person is potentially giving them more patrons, so it's in DPC's interest to essentially "partner" with them to produce more of this content and gets them more notoriety and more patrons.
