I'd been a constant lurker on head-fi for over a year before I actually joined. I didn't think my overall audio knowledge base was well rounded enough to make suggestions for others. In fact, I only joined when I wanted to sell off some gear. My FS ad was post #1, and join date said "today." I don't think I'm the only one.
I may be the exception, but its something to think about. Also, driving up post count isn't very hard. Additionally, if a scammer is patient (which I have no knowledge of weather or not they are) they create a few accounts, wait a month, then start scamming. While the suggestions may be slight deterrent to potential scammers, ultimately the buyer just has to check things out, ask for a phone number, really get a feel for the person. [From my personal experience, while real life scammers tend to be persuasive and charismatic in person (at least the good ones,) the internet scammers I came across were always horrible over the phone. Long gaps in conversation while seeing if they're contradicting themselves, then doing it anyway, overly aggressive, defensive and vague. That's probably one reason they stick to the internet, where they have as long as they want to get their story straight.]
By the way, for anyone interested, I have contacts with some Nigerian princes who can make you a very wealthy person indeed. PM me if interested.
