THIS IS A POST AS A MEMBER, NOT A MOD. AS FAR AS I KNOW, THERE IS NO SITE POLICY ON THIS
Please, before you link to an active auction, think to yourself "If I knew my buddy wanted this item, would I make the thread?"
I'm sure there is no ill intent, but posting auctions increases visibility, which increases prices. Maybe you are not bidding, but someone else may be (unless its a 10k overhoned rust stick).
Just a friendly consideration, that's all.
