Yup. No explanation from @Wikileaks either
(a two day delay after the original enigmatic tweet and kludging yet another reference to Hillary Clinton Goldman Sachs emails - hardly likely to be Ecuador's main concern - into the followup suggests that whoever is managing the Twitter account is more worried about managing the US election news cycle than anything else...)
There goes whatever credibility they had left. Ecuador shut him off, but they deliberately word the original announcement to make it sound like it was the US or the U.K. Good going, guys.
I haven't seen any word on their explanation, though.
