I'd leave the arXiv question open, because many people here will know and care about the answer, and there is no better public forum.
]]>However, the recent question Double referencing on arXiv is somewhat similar [added clarfication: to me it shares points 1, 2, and 4, not the others; yet these three are to me key-criteria]. (I, as well as at least four others, thought it was off-topic too; but then there was also disagreement, in some sense including from Scott M.)
So, it is certainly good to have a discussion.
[I did however not cast a vote, due to a at least temporary self-restriction.]
]]>So I've voted to close. Since someone has left a comment disagreeing with me, I've started this thread. (My hope is also that this will get it closed all the more quickly.)
