Background: these two FFO posts [1 2] gave the story of romance publisher Harlequin's dance with a self-publishing imprint, and the near-immediate threats from Science Fiction and Fantasy Writers of America, Mystery Writers of America and Horror Writers of America to delist Harlequin from their approved publishers list. The consequence of those actions would be that writers could not then use Harlequin publishing credits for membership into the those writers' professional organizations or participate in their awards programs. (There are speculative fiction subcategories in romance.)

Recently, Mystery Writers of America has delisted romance publisher Harlequin from its qualified publishers list, even though Harlequin removed its direct connection to the self-publishing arm by renaming it from Harlequin Horizons to DellArte Press. That link includes MWA's statement about their decision and Harlequin's reply. Earlier, Romance Writers of America delisted Harlequin, too, according to various sources. (The RWA requires a membership to read its breaking news section, so a link is not provided here.)

In a side note, here is an SFWA article (by way of Writers Beware) about the blurring of the distinction between self-publishing and vanity publishing.
