So? How is that relevant to what happened down your road, unless you've got proof that it was those bloody foreigners with their wash mitts near you coming over here and stealing our cars, jobs, women and Curly Wurlies.
Again, this is just an absolute nonsense thread with a nonsense title warning about nothing more than being stupid. Cars get stolen every day, credit cards get cloned every day, little old ladies get mugged every day. Even if it was a single racial group carrying out these crimes, are you just going to completely avoid anyone who might possibly be from there? I bet my house that there's more crime committed by white Brits than any other race in the UK, and I'll include car crime in that too. Doesn't mean I'm going start a thread saying WARNING WARNING SKINHEAD IN HOODIE IS GOING TO RAPE YOUR HAMSTER IF YOU LEAVE THE BACK DOOR UNLOCKED AND THE CAGE OPEN.
It's akin to those ridiculous email virus hoax warnings that rotate every few months or so, or the "Facebook is changing their privacy settings, please do X, Y and Z to stop it" crap that circulates. All it does is mean that when there is a real danger of something bad happening, people just ignore it because they're so used to seeing it.
I don't doubt your intentions were good Will, but perhaps a more useful thread would've had the title "Surge of car thefts in London N10" and the body text "There's been a lot of high-value cars stolen in N10 recently, please make sure your vehicle is secure at all times" or just something that wasn't blatantly trolling at pointing the finger with zero proof at a specific race of people.
