I don’t want this to turn into a devoted to my beef with the rules. I’m still looking for solid advice on purchasing a used arcade stick.
The rule is unreasonable without flexibility. It effectively limits decisions that should otherwise be made by two private parties. It attempts to construe length of membership as some kind of indicator for trustworthiness or reliability. Not only is the basis not of a kind easily construed to such noble qualities, but it stifles trade where the noble qualities do exist. This situation is a fine example of this; SRK is restraining a member who has real, quantifiable indicators of trustworthiness and reliability from engaging in commerce.
By extension, it’s preventing other members from deciding for themselves whether I would be worth trading with. While these members would likely be wary of someone who’s only met an arbitrary requirement to trade on SRK, they would probably be more comfortable with someone who has spent years trading on a dedicated marketplace with over a hundred transactions.
