yeah, that's pretty tough. I think my name on here is more important than a single deal. I made trade not too long ago, traded a guitar for an amp. The guitar arrived and had some damage, so I offered to undo the deal, but the guy loved the guitar, so I ended up just paying for the repair plus giving $500 due to the loss of value of a repaired guitar he'd face if/when he sold it. He didn't ask for it, but I thought it was the right thing to do. We've traded in the past and I'm sure we'll trade again in the future and that is more important than trying to stick someone on a 1 time deal. I think most people on here realize that, not sure what someone is thinking in trying to stiff another. Maybe it's just laziness, procrastination or maybe they are actually just dirtbags.
Even when I buy or sale something on Reverb or CL, I usually give them my name on here and Sevenstring and ask if they are on the sites as well. It's an extra layer of comfort knowing someone trades on here, because this kind of thing doesn't seem to happen very much (that I know of anyway) and it's a community built on repeated trusted deals.
