Apparently, KOSA's "knowledge standard" has changed from "reasonably likely to be used by a minor" to knowing that minors use your site.

The obvious problem with this (as pointed out by others) is that:

a) If a site simply knows that minors have been known to use their site, that could be grounds for state harassment.

b) As others have pointed out, if the moderation isn't perfect (particularly when it comes to removing a particular minor from a platform), or gets circumvented, that particular minor might be used in evidence and that *might* lead to liability.

This might be a problem for very large platforms.

c) Older minors are not the same as younger ones and any standard here is going to be a bit of an one size fits all solution.

d) There is still a big chilling effect on freedom of expression.
