After paying their dues, should hobbyists who committed fraud be allowed back ?

I'd take advantage of every lucky strike I can. Any seller who is offering an item for sale without knowing what it is or what is in it is foolish. Not the same as knowingly cheating collectors for years. But we don't need to get into these complex hypotheticals because the question is really simple: do we want people who've greatly and intentionally harmed so many collectors to post here? IMO, no. It isn't a tough line to draw. Card doctors, shillers, dishonest sellers and auctioneers, forgers...
