Seen quite a few profile photos of late where guys wanting to be discreet have pixilated or smudged faces.
It's worth pointing out that even the simplest of AI apps and tools can unpixilate giving a pretty accurate view of the original photo or close enough to say... isn't that...
I mentioned this to a guy I have met. He tried it on two of his pics where he had pixilated his grinning face. He quickly deleted and messaged back saying Fucking hell!
