It a shame that arXiv now it is not what it used to be, a very useful pre-print before actual publication. It looks like it is now a pseudo journal masquerading as a pre-print server since apparently arXiv has editorial and review teams that reject papers based on their 'expertises' [1].
Perhaps they think they are reputable now just because Perelman's proof papers were published there and they want to maintain their 'reputation' [2]. The irony is that Perelman would most probably not publish in arXiv if it is in their current pseudo journal status.
