Not outlawing something because "they'll just do it elsewhere" is just silly to me. Imagine if governments used that same excuse--it'd be anarchy. I don't think theymos wants to ban account sales, scams, sig campaigns, or anything else because those things bring in a lot of money for him, which is unfortunate. And Lauda has alluded to even darker motives, which I don't doubt.
Darker motives...such as?
