Got a source for that? That would indicate the only reason they haven't done it to Bitcoin yet is building this narrative / waiting for more Core 30 adoption...

About BSV from here

"After being told of the content by local authorities, BitcoinFiles.org removed it from its websites and gave Money Button the bad news that its service had been used as a conduit. Said Money Button:
We have confirmed that was the case and we have banned the user responsible for creating those transactions.
Money Button’s statement makes no mention of the type of illegal content, but the BBC confirmed that child abuse images were involved after talking to Money Button founder, Ryan Charles.
Why has this happened now?
The short answer is: because it can – the ability of BSV to store data recently expanded.
Money Button provides this service completely for free, and the only fees paid are to miners, which at present market prices are only about 7 US cents per 100 KB."
Seeing Core V30 percentage of the nodes I don't think they are able to propagate spam.
I hope you and the team can create the soft fork code without rush.
It needs to be well tested and very good quality to achieve the goal to protect Bitcoin from the spam.
