As to the matter of the slow bans. From what they explained before they don't want to simply ban the obvious small fries that show up. They do a lot of investigating and trace work in attempt to find sources. Or at least that's what they've said before.
While not 100% accurate, you can kind of tell the crafter/gatherer types that tend to buy the same stuff over and over and then see a retainer with 3-4 stacks of that item being sold or even when you see a lot of crafted items, look for the name.
