I think we should give sf a break. most scammers want a quick route to fast cash. typically, at the first sign of trouble, they run and hide. SF has stuck around despite overwhelming odds, haters and bashers trying to discredit him.
I ordered, I received, i'm happy. His email responses are same day, sometimes same hour. That's a bonus right there. In my opinion, SF, you're trying too hard. you can't please everyone all the time. People can be confrontational, prideful, illogical, or attention-seeking. You're going to have bad customers and good ones. the bad ones will bash you, and the good ones will praise you.
As it is with ANY UG, it's always a risk, no matter how established or long-running they are. Many start out good and turn bad, and many start bad, and turn out good. the problems lie with communication, miscommunication, impatience, and greed.
Just do what you do, and try to hold yourself to the same standards that you set on the first day, or even try to surpass them as your company matures. Customers will come and go. Just stick to your guns and don't retaliate. thats my opinion, not just for SF but for anyone out there.
