I don't think webmasters will be sued for this... Its your discovery.. and webmasters know a thing pretty well.. if something risky... what changes are required to cancel those risk factors.. lol !! there are countries where you can host your website... and everything.. which don't support no policy no rules.. Just you need to act smartly.. cheers
and when you get your website legally closed you are up with enough cash or profit... so chill out man!!!
