I’m seeing that BIP 444 was authored by someone calling themselves Dathon Ohm and that Luke Dashjr has denied authoring it. What is your evidence that Luke is the author?
Ok so apparently rolling back the chain in case of a CSAM OP_RETURN is also proposed as an activation mechanism for this “anti-spam” soft fork drafted by nostr:npub1lh273a4wpkup00stw8dzqjvvrqrfdrv2v3v4t8pynuezlfe5vjnsnaa9nk nostr:npub1lh273a4wpkup00stw8dzqjvvrqrfdrv2v3v4t8pynuezlfe5vjnsnaa9nk.
Also, even if no such OP_RETURN is mined, they want to activate this as a UASF within ~three(!) months.

It says at the bottom of the BIP that the original draft came from Luke. (And FWIW, even before I saw that, while reading, it was pretty obvious to me that that was the case.)
Has Luke denied this? (Where?)
It wouldn't be out of character for Luke to propose those but if so, why wouldn't he just use his own name. I don't see any attribution to Luke in BIP 444 but maybe I'm just missing it. Here's a link to the article that says he denies being the author
