to be fair though, vendors can't force people to read their listing description, and also can't force people to be smart. some buyers don't read anything and then don't think, and end up putting their info. i've heard of buyers providing their name, address, email, and PHONE NUMBER to vendors, unencrypted, for digital items! so ... i don't think we can blame any vendor for what info they end up receiving from buyers who don't know better. also, i appreciate that you're trying to warn people to help keep them safe. that's noble. but just because we are on the "darknet" doesn't mean that the marketplace is devoid of selflessness. my best guess is that she's providing the info for free for the benefit of the marketplace. plus, she mentions that people who are interested in a guide about obtaining bitcoins are probably not going to have bitcoins already ... so it might technically be pretty difficult for her to actually sell the guide. even as a moderator, i've received PMs with people sending their info for whatever reason.
