Well, lot of grey stuff can be shared with little-to-no restrictions over the internet (any pirated stuff goes pretty much unpunished, except for the occasional exemplary lawsuits). If you are paranoid, there are lotsa VPNs for affordable prices, with various anonymity levels. The only thing that really needs such anonymity to share is hard illegal stuff, which will put you in prison if you get caught. Such sites don't really have any other realistic usecase, so not really sure what were they thinking...
