Tube Crush, are you some strangers crush?

tubecrush.net is a website of great fascination to myself and others curious interested in the cctv nature of the western world. The website where people post pictures of strangers on the tube of interest, or of whom they take a liking too is becoming increasingly popular, in fact it has even come up in an article on the bbc news site. 

Despite the light natured theme of the website, there are serious legal and moral qualms surrounding the use of strangers pictures without their permission. The tfl suggests that the underground is a public space and that it is infact legal to photograp people in this nature. the producers of the site say "We hope people take the site in the spirit it was intended - it is not to cause offence.". It can be said that this site is more of a celebration to the spirit of the underground and the growing popularity of social networking.
