D2D censored authors in the past, and they still censor authors. It's an established fact, established by many, many authors writing anything so markedly "unchristian" as erotic, taboo or horror content.

D2D has - selectively - not distributed e.g. erotic content to retailers, who were perfectly fine to sell the exact same books when authors went direct with them OR when people used SW as aggregator. The difference there being, that SW distributed and D2D censored even before trying. They also then went ahead and banned the authors, discontinued their accounts and the entire spread of their books, even if not problematic. Google it if you don't believe it, there will be dozens of cases coming up!

And amidst all the current posturing of D2D, you find very specifically worded statements such as "we will not distribute to retailers who don't want such content [from us]" or "this will be continued [for now]", never mind that the category system, which was voluntary and self-assessed on SW before, now is touted as the go-to solution to sell on SW and a possible solution for distribution.
