yes! i learned RSA-based time-lock approach to tell GPUs "fuck you". its also much easier to understand and implement than fancy Verifiable Delay Functions
and IMO we also need to run cheap classifiers in clients or relays. the advantage of running a cheap classifier in clients is that... they can also make their classifier personalized by marking the content they find personally annoying. BUT I DON'T KNOW HOW TO FUCKING DEAL WITH FALSE POSITIVES AND FALSE NEGATIVES. I HATE THIS
