Website in question is appykidsco.com. The linked story suggests that the domain has expired and these ads may be common for the webhost. They only appear in mobile mode.
If you manage to find an image of the box in high enough resolution it's appykidsco.com
Good call on the mobile mode trick. I initially saw the chinese page (that google couldn't translate so no idea what it was) and there was no porn there.
It died some time in 2022, was a blank page for some time then presumably expired and started showing chinese at the end of august this year (or at least that's when wayback machine picked it up.. the domain entry was last changed in February).
