Interesting to see from page 1 of this thread, 6 years ago back in 2013, the same discussion. A poster back then was concerned about people new to silver stacking getting ripped off, which is the same concern I have. I understand it is impossible to monitor, who decides how much is too much etc etc. But just because somebody has a high post count does not mean they are trustworthy. Occasionally I see sales threads that make me shake my head, so I've just built my own "never buy from that person" list.
