The NeurIPS exemption isn't specific to arxiv: "The existence of non-anonymous preprints (on arXiv, social media, websites, etc.) will not result in rejection" People can post anywhere. Most people don't. I don't check carefully, and as I reviewer I explicitly don't look, but when I do see a preprint it's rarely any different from the submitted version. People do stake out territory, but it's more like they do that with shitty papers that no one wants to accept but they want to "own" some phrase that might be popular in the future. The NLP community is very unhappy about this in particular. > I just wanted to point out that this does vary a little bit. RSS was double blind this year but ICRA was single blind last I checked. It has been this way for a few years now. RSS & CoRL are double blind, ICRA and IROS are single-blind. I can't think of the last time I submitted to an ML, AI, NLP, or vision conference that wasn't double blind. It's sort of a strange robotics thing :)
