What frustrates you the most about seller’s for sale ads?

"Then there is the kind of would-be buyer who disingenuously posts questions” taking issue with the stated condition of the equipment, and/or insinuating it is overpriced due to the  lack of original packaging or some other marginal detail. I doubt Audiogon much appreciates such self-appointed equipment police, who inhibit site commerce just so they can take potshots at others’ expense. Instead of dissing the merch — and the seller — move on to the next ad and leave it at that."

I personally don't comment on the price of for sale goods; value of an item is to be decided by the buyer. However, I DO take issue with  ads that do not honestly state the condition of the equipment and give it an appropriate numerical grade. When I see it, I point it out to the seller, and will continue to do so. If sellers won't "police" themselves, then other members like myself will have to police them.
And by the way, I have never had a complaint from the moderators for doing so.

Speaker ads with one or more driver dust caps or tweeters poked in by a toddler..."does not effect sound".

"Rare". Rarity does not equal quality, and it means the piece will be difficult to find parts or repair for.

Sales pitches presented as an opportunity for the buyer, when the seller is the one looking to unload this stuff.

...”almost Everything”...almost Everything is Wrong...which sometimes leads to good comedy on this site. 
But there are truly some very good Audiophiles selling at very reasonable levels, and that alone keeps me returning to search for the “right” gear. Can I hear an “Amen”

Mine is a basic one:

It bugs me when sellers don’t say why they’re selling an item. I always want to know and sometimes lose out on an item whilst waiting for a reply.

Are you “upgrading”? That’s useful to know because maybe the item isn’t as top of the line as I think. Does an amp not work with your speakers? Maybe I have the same ones. Etc, etc.

They don’t have to write their life story, but it’s nice to know the motive behind the sale.

That never bothers me. It used to when I was new to the game, but now I realize that just because the seller wasn't happy with it doesn't mean that I won't be. Now I'm only concerned with the condition and the price.
