I think something needed to be done. I have noticed several new members selling dog every other day, and also posting wanting to buy posts. I think they need to be a member for a certain amount of time or post a certain number of posts before they have the privilage to post.
The problem with a post count requirement is this.
Good hog, good hog, good hog, good hog, good hog, good hog, good hog, good hog, good hog, good hog, good hog... finished dog for sale $5,000... meet me at Dairy Queen.
They just post BS posts to run up the count, then BAM they have some finished dogs, they are selling out, etc.
