I know the mod's are busy guys these days, but if the resource were available, a 'FS thread specific' moderator would be handy. Mods could take it in turns for any given length of time to solely concentrate on modding the for sale threads, and should someone post a derogatory or unhelpful comment, just remove it. Simple.
Personally i would rather be able to comment on FS threads, or at least read other comments. As said before it does help to give you an idea of what you are looking at. If i was looking at an ad for a 'mint' sport for example, and it was a locked thread like on e36coupe, i would have no idea whether it was any good or not. If Barry or brian came along and said 'i know this car, it's a beauty' etc. you would be more inclined to go and have a look!
Unfortunately, open internet forums and social networking sites have opened up a whole new playground for certain types of people to quickly and easily put down and ridicule others for personal gratification. If you wish to be part of this kind of culture, you must be prepared to come across these characters and have skin thick enough to let it slide.
Sorry for the rant, just wish people on here would chill the fook out sometimes, we use the zone for fun, why must it be so regimental!
