Yeah, nobody would consider an arXiv-only article by an unknown author. There are plenty of P=NP "proofs" published on the arXiv. But that isn't what it is for. It's a preprint server where you have to do your own quality control. A lot of work in the theoretical CS community is published in conferences and on the arXiv, often in extended form (additional proofs, plots, etc that didn't fit into the conference publication's page limit)

From https://arxiv.org/help/general: "Disclaimer: Papers will be entered in the listings in order of receipt on an impartial basis and appearance of a paper is not intended in any way to convey tacit approval of its assumptions, methods, or conclusions by any agent (electronic, mechanical, or other)."
