It's been a matter of time. A platform that has been recently recovered by big companies and their public relations agencies now attracts jurists' attention. Minors visiting virtual brothels might become a serious problem for SL maintainers if the site owners don't offer protective measurements. Accoring German law, this would mean distribution of pornography to minors and this is actionable. Additionally, having sex with avatars that appear like animals, or children, would be a crime as well. Even if an avatar looks like an animal (though being a complete fantasy character) would be harmful if it would have, say, testicles and it is using them. This is a rich field of activity for prosecutors and you better watch your avatars - if you're playing SL in Germany! (Source: Interview (German) with jurist St. Mathé from Hamburg)
