This has probably been considered before, I just don't have the right search terms to find it, but what do you think about modifying the forum code/rules so that users with negative karma aren't allowed to lock their for sale posts regardless of contributor level? It seems like this may be a good way to offer more protection to buyers by being able to alert them to bad guy threads where the bad guy has received overwhelmingly negative karma.
Under the current system a user can list stolen animals and as long as they aren't breaking any site rules, they can lock the post and offer themselves total impunity to anyone who doesn't start digging.
