Make it so that the account section is visible to people with under 100 posts but that they can only see and post in price check, if of course under the 100 post count. In the price check section you can have a thread stating rules and requirements of selling accounts, 100 posts etc. This would hopefully prevent new people coming on and posting their account sales and price checks in the graphic section or elsewhere while also allowing new members to get price checks while being able to build to 100 post count and the ability to sell their account. With this new system strict rules should be put in place that you if you buy an account from a member who does not reach the requirements to sell and you only found the account due to it being in the price check section feedback or scam appeals should be invalid as both members have broken the rules. An announcement should be made to members telling them to wait for the poster of the account in the price check section to get to 100 post count before buying to ensure a safer transaction that feedback can be applied to.
