A stone or insert in your shoe would probably work (albeit painfully). I don't think people would think you were actively dodging ML if you had a limp, unlike strange face painting or haircuts.
I've been looking into anti facial-recognition make up, and I wonder how much you'd have to apply to defeat the algorithm - like, would a line of make-up breaking up the contrast pit of an eye be sufficient?
And then there's reflectacles - glasses designed to reflect IR and visible light. I presume they'd mess with an algorithm, but could you code that algorithm to recognise them and raise a flag requiring human input?
Ah man, I love how the cyberpunk dystopian future of my youth has slowly arrived, sadly with less magic and orks, and last I checked, no shady street samurai in bars looking to hire me for my leet decker skills.
