Yeah, here is some advice ... don't advertise on a public forum (here) and with your working name and links, that you are about to break the law in another country, a law that can result in up to a year imprisonment. The Swiss mean business. Why do you think you got the RM pop up?
They even have disallowed for commercial sex workers from abroad (ie outside EU, Schengen) the 8-day per year transnational working privilege that is loosely in place for other occupations. The countdown for erotic entertainment commences Day 1.
Enjoy the sights in Zurich and around there. Fantastic. Avoid the sites.
