Filters don't work 100%. We al know that, but that doesn't mean to get rid of them. First of all they work for most cases and second of all they give you plausible deniability if illegal spam gets through. Doing nothing is saying your CSAM is welcome on the blockchain uncoded.

Yeah, but if core start willingly releasing code with bugs, you have to look for an alternative. Knots or don't upgrade. I don't like to play it on the person. I don't care if the maintainer is a catolic with a beard or some meme-chick.

Yes, but that has nothing to do with the code of Knots. While in Core30, there is a bug where transactions with multiple op_returns will not be seen as 'non-standard' anymore after the change. As described in this PR. https://github.com/bitcoin/bitcoin/pull/32406/files Why core is not adressing that is beyond me. They just pushing it through...

Judge the code, not the man.

If Core implemented a spam filter, Knots wouldn't be so populair.
