Wikipedia says the operator refused to voluntarily work with law enforcement to give info on the Christchurch shooter.
Is that incorrect? Or are you just saying the operator responds only to warrants and subpoenas? I wouldn't call that "working with" law enforcement, I would call that staying within the bounds of the law in that particular matter.
Maybe should have specified 'US' law-enforcement as it's a US site ran by a US citizen.
The citations on Wikipedia are interesting though (from the perspective of what's considered a reliable source when it comes to controversial pages). e.g. [19] says that the operator was "allegedly removed for promoting paedophilia". The same guy that wanted to ban discussions about 'VTubers' because some of their 2D models looked too young and might attract pedos to his site. So take that with a grain of salt.
