But here MOGIS cheats as well: Depending on where the page is hosted it might not be possible to delete the pages and sue the operator.

Yes, but to every rule there is an exeption.

This was also tested, and even back then - 9 years ago - it was possible to delete such pages even in "backwater countries" for 90% in one day and nearly 99% after a week, not even using legal threats but just alarming teh hoster (which the filters would not do btw.).

So for all practical means it was and is possible, and oftne easier, to delete than to block.

The government used a false dichotomy

No, they bet on the simple fact that 90%+ of people did not know anything about what they were asked ;) They just heard "child porn" and shouted YES!

Not a dichotomy, not telling the important parts.
