Unfortunately, they thought of that. Some of them are known answers that they use to be sure you're answering honestly. They'll fail you on those even though they know you're not a bot.

Fighting the fire happens after stopping the person lighting the fire. Focus on the immediate threat, don’t get distracted by the lofty long term.

I would hate that case.

yea i also were there at a few thousand I think and the content has changed a lot since then.

I think you're missing some key points. Any file hosting service, no matter what, will have to deal with CSAM as long as people are able to upload to it. No matter what. This is an inescapable fact of hosting and the internet in general. Because CSAM is so ubiquitous and constant, one can only do so much to moderate any services, whether they're a large corporation are someone with a server in their closet. All of the larger platforms like 'meta', google, etc., mostly outsource that moderation to workers in developing countries so they don't have to also provide mental health counselling, but that's another story. The reason they own their own hardware is because the hosting services can and will disable your account and take down your servers if there's even a whiff of CSAM. Since it's a constant threat, it's better to own your own hardware and host everything from your closet so you don't have to eat the downtime and wait for some poor bastard in Nigeria to look through your logs and reinstate your account (not sure how that works exactly though).
