Note, interestingly, that the censorship began immediately after the site's restoration from the previous shut-down which had been covered by several media sources  it appears very likely that the shutdown (blamed on a "technical error" despite the fact that there seemed to be public indications of a retirement of the site through the "RIP" posts) and the censorship have some connection with one another, although this isn't really a useful place to speculate on what that connection might be. I can mention that most people in the community associated with ED express the belief that motivation for more ad revenues is the cause for censorship, as the site in its more explicit form had much difficulty finding sponsors, although there is no official word yet confirming this and I wonder if it's actually the case, or if some dispute with a legal or corporate authority regarding content might in fact have been the trigger. I can find no third-party sources presently which discuss the new censorship as of yet.
