Selling on here should be a privilage not a right. So I think all 3 is the only way to go. A month and 50 useful posts is not really enough by itself to keep people out who just want to sell. If it isn't broke why try and fix it? I've seen quite a few posts in my short time here where people post a pic of someting then say now show me some green. They never get it they get warned about neg rep instead. So since you have to earn it actualy it works great. I gave it to Fonz because of a good point that I liked, and I know hes not fishing for it. So IMHO he earned it.
