I think the main point to line "NOTICE: If you use the shipping options for anything other than their intended purpose, your account may be terminated. " is to say exactly that using shipping fees for anything other than shipping fees will result in your account being terminated. It's to avoid things like the old (and sometimes current) ebay scams of pricing the item for free, or for $1, and then charging hundreds for shipping. You, in theory, avoid selling anything prohibited, since "you're only selling a box with the free item in it" and still making your money on "the shipping fees".It's to avoid the deceitful use of feature. If you legitimately need to charge extra because it costs you extra to have in imported/transported etc, then be prepared to justify the higher rates if asked.
