I guess I'm just naive or extremely lucky. I've never had even the slightest problem with the FS forums, both buying and selling. Is this really that big of a problem?
Also, is it really so terrible to buy and sell stuff in rapid succession? One of the things I love so much about Head-fi and the FS forums in particular is that it gives me the chance to try new stuff. Buy it, try it, don't like it, sell it; what's wrong with that?
Double accounts, lying, cheating, stealing, etc are of course all bad things but simply buying and selling stuff shouldn't be a problem.
Again, I don't know if its naivety or just luck, but I'd be really shocked if this is such a wide spread issue. I hope Head-fi isn't in a "downward spiral" because I sure love getting up every morning and scanning the latest posts, often in the FS forums. I don't "need" anything, but has that stopped any of us before?
