When I sell, I usually check the posting history of the buyer. If everything they have done has been on the ticket exchange, that screams scalper to me. Since I typically don't gouge, I don't want a scalper buying them from me and turning around and selling them for a 250% markup.I've only had great experiences on here buying and selling tickets, but there seems to be more new members with no other posts now selling tickets. I don't remember that being the case in years past.
