Deletion of Doug Turnbull (author)

Comment: writers whose work is primarily self-published or vanity-published are rarely notable.  No indication he passes .  I also strongly suspect a Spam/COI issue as well

Comment: I see no significant coverage about Turnbull in independent reliable sources.  Being a self-published author does not bar Turnbull from meeting Wikipedia's inclusion criteria.  However, as an author (self-published or otherwise), an article is only justified if  or  is met and fail to see how either guideline has been met in this case
