I think it rarely stimulates people to discuss and reach a positive outcome. I have seen some nasty ones on here where sellers have told very one sided stories, preemptively badmouthing buyers just because they don't want to take a record back. Whenever I sell anything I will always take it back if the person isn't satisfied -- there's always someone who's a more conservative grader than you, for example, and coming online and accusing them of trying to switch out the record or something before you've even gotten it is just nasty and reflects poorly on you as a seller. I'm speaking in general terms, not referring to anyone specific here (please don't get offended anyone), but it usually comes off as very nasty and unhelpful. If you're a seller and you get your record back and refund the buyer, at worst you're just out postage and have to resell the record. If you're a buyer and get screwed, you're out a lot of money and are potentially stuck with a record that is worthless to you. I've had people send things back to me or even ask for discounts (sometimes warrantless) and I always agreed -- and I've even later seen the same people overgrade records (selling to me!) or resell the same record they asked for a discount on for much more ... it still didn't hurt me that much to comply. Unless it is a real situation where something has done something really and clearly bad / illegal (e.g. fraud), it usually doesn't accomplish much to come on here and badmouth people.
