The requirements for post count and length of membership are designed to limit those offering sales, purchases, or trades to members who have been around the forums enough to become known and have an investment in their MacRumors membership that they are unlikely to want to risk. Although new members or members with fewer posts may be perfectly responsible buyers or sellers, other members have few ways to confirm that at MacRumors. The lack of a post history in the discussion forums has proven to be a detriment to successful dealmaking. The requirement for length of membership will not be an issue for most members, but discourages rapid posting by new members who might try to build their post count to gain Marketplace access quickly.
