I'm sure the vendor turnover rate on here is quite similar to the vendor turnover rate in the f2f blackmarket. The biggest players remain and the lackeys come and go.I know a few vendors here have gotten in legal trouble (unrelated to SR but takes them out of the game). That's always a risk.Before some of the buyer info was up scamming was fairly rampant and sellers were getting ripped off (also direct-BTC-transfer has mitigated this for established sellers who offer pretty significant discounts for opting for it), and I remember even a few of the bigger ones packing up shop as a result.It's also very time-consuming when you start doing heavy volume. Just driving to different postal outlets to keep from establishing "a pattern" if you packages ever get noticed can eat up several hours a week. Not to mention packaging times, printing envelopes and labelling, etc. Communication on here is pretty huge too. And with so many new customers coming onto SR in a steady stream (or a massive gush a la Gawker et al), there are dozens of questions to be answered, disputes to be addressed, etc.It's a lot of maintainence.I will admit the margins standalone are definitely better for me, which is why I continue it. But it pretty much balances out if I were to calculate a wage out of it, I may even "make less" from SR when approached from this direction. I sell one pound of product f2f, takes me half an hour and I make three or four hundred. On SR I have to answer many customer inquiries, put together 5-10 packages, ship them out, buy packaging supplies frequently, etc. etc. I don't sell much small scale in the f2f world, not even to friends (My friends don't know I sell). I also keep it up because it's fulfilling to take a shit on the false concepts that the state tries to build - that drug trade is in and of itself (without prohibition being considered) a dirty, violent, etc. thing that is a huge detriment to society. Every time I refresh the page and I see a new set of completed transactions a smile comes to my face. That's x number of times more the state has been rendered impotent, useless. That makes me happy. I like to participate in things that make me happy. You see how it works ;)
