Craigslist really is a roll the dice, i've sold computers cars etc on there and you really have to be careful. I guess you have to be attuned to how the person is acting about the trade. I personally would never sell bitcoin on craigslist
The spam one gets from craigslist is enough of a deterrent for me to stay away unless I'm having or looking for a fire sale.
The amount of spam that you receive when you post something on craigslist is insane. They should really almost have some kind of capsha that would prevent spam.
