Selling or posting an add on this site

10 meaningful post (conversation ) and 10 days on the forums , doesn't need to be consecutive days , but 10 days total to buy or sell
To buy, doesn't seem like such a big risk. The seller should receive and confirm payment before shipping. To sell immediately, that is certainly a risk to the membership and new members who have any experience with the issue (we're not the only forum with a classifieds) will understand and participate.
 
As a new member and a person that usually just likes to lurk, the 10 day thing would be frustrating to me if I wanted to buy something from someone. But I'm also not planning to sell anything either, nor would I expect to join a group, post up an item for sale, then just disappear. There are sites for that already (ebay and gunbroker). I can definitely understand the reasoning for the rule, which is not bad by any means, and looks like it does a reasonable job of keeping away the bad people.
