This plugin by Saguaro Digital restricts content which isn’t appropriate for all ages. The [Association of Sites Advocating Child Protection (ASACP)](http://www.asacp.org/ “ASACP) has developed the Restricted to Adults (RTA) tag which most online protection software respects.
Installing the RTA tag on a WordPress install can be somewhat complicated, so the Restricted to Adults plugin makes it one click — activate the plugin and your site is restricted to adults.
