+	  <p>A malicious or poorly-implemented homeserver can inject malformed events
+	    into a room by specifying a different room id in the path of a /send_join,
+	    /send_leave, /invite or /exchange_third_party_invite request.
+	    This can lead to a denial of service in which future events will not be
+	    correctly sent to other servers over federation.
+	    This affects any server which accepts federation requests from untrusted
+	    servers.</p>
