You make a great point, insick. This has happened to me in front of people I know. I just laughed it off and we all got on with our lives. What they think of me is their business, not something I worry about. Someone once sent me a dick pic which I opened in public too. It taught me to only click on trustable people when I'm surrounded by witnesses :P

Dunno if it's obvious yet, but I'm against any form of censorship :D
