Your individual mempool policy is irrelevant if it still gets mined. Leave the CSAM FUD out of it. So what if you don't relay it (you are still caching it) but it still lands up on your node anyway when the transaction is mined.
Miners don't care about your signal, they are trying to make a profit. They will mine the most profitable, valid transactions and that incentive is what makes Bitcoin work as permissionless, censor resistant money.
The ONLY way to prevent this activity is to fork and make these transactions invalid.
I'm not telling you not to run knots. Do what you like. Just don't think that you are preventing anything. You're not. Just virtue signaling.
