Honestly I doubt they unlisted it to manually review, its more like "oh we have very little time, lets do this to buy time" as they can then try to figure some long term solution out. The deletion of content that dont abide by laws to begin with is kinda an aside, more of a sanitation thing which might help protect them if they're to be reviewed externally later or make a case for why Visa/Mastercard should allow the site to use them as payment processor.
I'm not arguing against this being about the UK law and payment processing, but its way more aggressive and a level above incest content, and more about adult games being accessible by minors at all. Unfortunately we'll either see heavy region locking, or requirements to identify with government ID's in the future, something that no sites really have the infrastructure for and is so incredibly unsafe security wise. And lawmakers and lobbyist KNOW this, which is why they're pushing for it as it means effectively banning it on the pretense that "oh they cant comply"
