Why is it that we aren't revealing information about the DNMs that could lead to their compromise? Why can we blatantly talk about our recent purchases and vendors can advertise their products? Why haven't the LE figured it out yet? Or rather, what is it that prevents the LE from doing something about it.
LE most likely monitors this subreddit. However, we don't discuss things here that they don't already know. What kind of information is being given out that could bring down Agora, for example?
If people are practicing good Opsec they are using a reddit account created through tor and only logged into through tor when they talk about recent purchases or post vendor reviews.
I personally feel that vendors who advertise on reddit should take extra precautions.
I'm not really sure what you mean by this. LE is certainly aware of this subreddit but it is not illegal, it is merely a place for discussing DNMs.
