just inject this with your favorite JS injection plugin
let oldTanh = Math.tanh;
Math.tanh = x => oldTanh(x) + Math.random()/10000000;it's elegant, but i prefer:
Math.tanh = Math.random;Great, now you'll be outed as "hides fingerprint", which is probably more identifying than if you returned a normal value.
Multiple anti-bot vendors will detect that replacement and use it as part of their fingerprinting process.
