I don't know why this didn't occur to me before, but you should be able to use 4chan through Tor if you use a 4chan Pass. Which requires money. It can be paid for with crypto, but CURIOUSLY not Monero.
I probably wouldn't give money to 4chan though. But it's a way to get around rangebans and shit, people use it to use rare VPNs that have permabans on them so they can get North Korea or China flags on /pol/
