My reading is they don't even need to verify age. The bill refers to users the platform "knows or reasonably should know is a minor" all over the place, and has a bit about a feasibility study for age verification (which can, of course, be done in a privacy preserving way). Unless I missed a particular sentence that didn't include that language, it seems that it's more that if the user tells you their age, or if you are a giant advertising company that stalks everyone in the world to build profiles on them and you determine through your nefarious activities that someone is a child, then you need to take that into account. If you don't collect information on your users, then you don't know they are minors. The main sticking point is probably (some) games and child focused spaces where perhaps you should reasonably assume they are. Basically, they need rules that even the likes of 4chan have enforced for decades: mention being underage, or being in high school, etc.? Banned (or in these cases, set to child mode).
