My kids similar, my now 13 year old has earned more than 1mil robux from a couple of games he’s made. That doesn’t discount the fact that the block is there and effort is required, rather than have it shoved in their face by scummy click-desperate tech bros and pron sites..?
I suppose it might stop a bit of it. The biggest impact is probably that it prompts a few parents to ask their 10 year old why they have a VPN on their laptop.
That would be good. I come from a perspective of being a developer most of my life a lot of it web based.. I think it will stop way more than a ‘bit of it’. As for sites that ignore the age verification.. Sanction them, close and seize their UK/EU based accounts / servers. Finally firewall them.
