I'm aware of viXra, but that doesn't have the feature that arXiv has that subscribers to a given list get daily lists of new abstracts, which is why reclassification combined with 'this paper is inappropriate for crosslisting' is so regrettable. Actually, there is an appeal process you can find if you look in help, something like emailing moderation@arxiv.org, and I appealed successfully once this way when a submission of mine was totally barred.
If you have a bit of time to spare, you might find the following articles enlightening in regard to arXiv:

Covert censorship by the physics preprint archive (extract follows)
It is just an ordinary day at the headquarters of the physics preprint archive. The operators are going through their daily routine and are discussing what to do about recent emails:
'Some "reader complaints" have come in regarding preprints posted to the archive by Drs. Einstein and Yang. Dr. Einstein, who is not even an academic, claims to have shown in his preprint that mass and energy are equivalent, while Professor Yang is suggesting, on the basis of an argument I find completely unconvincing, that parity is not conserved in weak interactions. What action shall I take?'
'Abject nonsense! Just call up their records and set their 'barred' flags to TRUE.'
'And here's a letter from one 'Hans Bethe' supporting an author whose paper we deleted from the archive as being 'inappropriate'.'
'Please don't bother me with all these day to day matters! Prof. Bethe is not in the relevant 'field of expertise', so by rule 23(ii) we simply ignore anything he says. Just delete his email and send him rejection letter #5.'
