I have been a member here for several years and have 6K posts many of which are classified transactions, I have only had a handful of deals that have not gone smoothly. I.E. buyers remorse,changed their mind,never responded etc., if you a re going to buy and sell you kinda have to expect these things. 50% transaction problems seems awfully high, as time has gone by more people have discovered the 'Fire classifieds these folks may not be the caliber of the older 'Fire members, don't know. I sell on a couple of other sites but far less than here and have not had any prolbems there yet but the volume is far less.
