Ask HN: ArXiv Endorsement as Independent Researcher

I have a preprint article [1] which I'm trying to get submitted to arXiv's cs.SI (Social and Information Networks) for peer review. As an independent researcher I do not have any affiliations to a university anymore. How do I go about this? Appreciate any kind of info / support.
