In Germany, a contract for such a service would be legally void.

(An example of this is the sale of radar detectors. Here, too, the companies claim that it’s the user’s responsibility not to use them for illegal purposes, i.e. speeding. But the courts don’t buy it. They say the companies know exactly what they selling, and they declare such contracts void. The fact that a user could, theoretically, use that detector in a way that would not be unlawful is irrelevant, since it’s empirically evident that the vast majority does not, and the very appeal of the product is precisely the unlawful behavior.)
