After hearing the idea, I believe that it is not at all dangerous.
Same here. However I advised Eitan to not make a post about it, because the potential, however small, for negative publicity ("look what these crazy LWers think up") clearly outweighs the potential benefit (vanishingly tiny). I suppose a question in the open thread would be OK. The thought is neither very original nor particularly interesting.
applauding your choice to err on the side of caution.
i absolutely agree here.
Out of curiosity, did you make this recommendation before or after reading jimrandomh's comment? I ask because I think that his comment would have caused me to have an "appear to be even more cautious" bias.
I'm interested in discussing this with someone, non-publicly. It's safe to know about personally, but it's not something I'd like people in general to know.
I'm really not sure if there is a protocol for this sort of thing.
