If the sale thread is properly done there is no need to Delete if just for comments. Just delete them. If the sale thread is not proper, contains personal information, wrong forum or worse yet, a sale in a non-sale forum, lacks photos, descriptions, price, etc the thread "may" be deleted. For me it all depends on how many rules were broken. If it only has one issue we try to get the seller to correct it. If it has a bunch of things wrong the seller needs to start over and re-read the sale rules. Also. it wouldn't be fair to the seller to delete the sale thread just because other members don't follow the "no comment" rule.
