I've already explained to the server admin/owner and he keeps insisting that its a "US-only law" despite even being directly linked to the international scope portion of the COPPA wikipedia page, its gotten to the point where even his Ops are under the impression that they, as a server, are not liable for players under 13 joining and playing on their server purely because "buying an account for Minecraft requires a transaction through a credit card or bank account, which both have you require being an adult, so technically, all Minecraft accounts belong to adults, so COPPA doesn't apply to Minecraft."
