Got ratted cos he was tatted?

Was going to post this on the Weird News Stories page, would be at home.

But after reading it, was curious about how he still actually got caught? They say his tattoos, not his face which was covered, gave him away on YouTube. But, who was watching the video on YouTube and reported it? Doesn’t say, explains no further.

That had me thinking, perhaps there was no one watching and perhaps youtube are running software to recognise not just faces but other distinguishing features? And are they then potentially selling that data to authorities?
