Related issue: AdguardTeam/AdguardFilters#156794
||new-in.pmirnc.com/public/fingerprint2.js$script,redirect=fingerprintjs2,importantThe above filter does not work on the website.
The anti-adblock script requires result of a visitor's environment named as components variable.
Its server requires result of x64hash128 hash function to proceed.
It seems that it is okay to return random int for the hash function if the server does not track the visitor and check its value.
