This would make sense if we were making an exhaustive list
Why would that make sense? It makes sense to point out common ones. Especially if you are, presumably like the people at Recurse are, informed by the experience of running that type of learning environment. They aren't trying to be exhaustive or all-encompassing or even a downer. They're trying to deal with problems they've encountered, not writing a formal system of acceptable behaviour.
This would make sense if we were making an exhaustive list of "potentially reflexive behavior which people may engage in but should not in this community", but keeping such a list in your mind is one hell of a downer. The best rule to encompass this, I think, is "epower those around you". Noisebridge has an even broader social rule / ethos which has served them well: "be awesome to each other".
Love the community at Recurse, but having social rules be a list of shitty things someone once did is the least awesome part of Recurse :-)
