Aren't there any rules about posting for-sale items? In the last few weeks alone, at least 2 people have joined the forum and posted items for sale, and have made no other posts.
My proposal:
To post for-sale items, the following criteria needs to be met:
1. Be a member of this site for at least 3 months.
2. Make at least 50 quality posts within the last 3 months.
3. You have not posted a for-sale item in the last 15 days.
If nothing else, maybe we will start to get more activity on this relatively quiet site.
