Where is the need to do that specified in the actual bill? https://leginfo.legislature.ca.gov/faces/billTextClient.xhtm...

the majority of the bill is restrictions on collecting personal information in general

I'm not sure most ecommerce sites would meet the criteria as something marketed and targeted at children

I agree that 'likely visited by children' is nebulous but this seems to be heavily aimed at live streaming/recording services(twitch, tiktok .. etc), large public social forums (discord) and things like youtube kids
