I hope you are not worrying about this for the wrong reasons
hope you are a legit member
If you mean spamming or scamming I'm certainly not planning anything like that. Part of it is that I like anonymity, but darknets user numbers are too low in general (on forums etc)
For example, I wish to procure some specialist professional services in a way that they cannot be linked back to me at all. Bitcoin seems an ideal vehicle through which to make the transaction (via a mixer), but I still need to be able to advertise the requirement somewhere, hence signing up here.
btw, found this post quite helpful:
