Just get someone to write a userscript for you.
A script like this would be very beneficial for everyone.
Whineposters can circle-jerk in complaining about how shit this board has become while hiding every other thread that isn't a whine thread.
Incels and r9k fags can hide the whineposters threads and circle-jerk in their edgy shitposting.
Mugwumps like myself can hide both types of cancerposting and join threads that discuss topics that are really worth my time.
you can't (or rather shouldn't) use scripts on tor
anything out of the ordinary marks your fingerprint in a different way
