Privacy and Community Norms

So apparently some guy baited a fetish community the online personals [see zuzu in comments] at Craig’s list and then published all the replies he received in full, which although it has generated a lot of disagreement but strikes me as unambiguously wrong for the reasons stated by Labs, and it also probably (and justly) illegal. I’m also not sure if the people who sent the info were, given the norms of their community, being as imprudent as some people asserts. Admittedly, I’ve never used online personals, partly because I’m fairly obsessive about privacy, so perhaps I’m wrong. But wouldn’t most who used personals for any length of time acquire plenty of potentially embarrassing information about people that they would just as soon not have made public? It seems to me that it would be pretty common for men to send some identification of job, etc., relatively quickly so as to counteract the creepy-unemployable-loner-living-in-mom’s-basement assumption about internet love-seekers that may obtain in some quarters. Obviously, narrow communities of perverts are the most vulnerable, but if it were me I would think twice before blaming the victims here; pretty much any such community involves an implicit trust.
