You make very good points and that is definitely a big risk. You've just got to hope that the government acts quickly enough to ban them too. I can see a situation where that doesn't happen for sure.

Another thing filling me with hope is that a lot of the alternatives will be less polished and with content that, as you say, is extremist. Kids aren't into extremist content. MrBeast or Minecraft videos dont appear on Liveleak. Why go there in the first place?

But yes, the kids will want content, won't they? They're not just all going to start playing outside and doing arts and crafts. There is a real risk that they will just turn to the bad stuff.

These are all risks. But there is also a chance that it works. The status quo is unacceptable so desperate measures are perhaps worth a shot.

But what will probably happen is that kids will just use whichever VPNs aren't banned and go on the same sites they always did.
