Just looking at the other RFC's, it turns out the "packet mood" RFC also allows one to flag the packet as evil: https://datatracker.ietf.org/doc/html/rfc5841 https://datatracker.ietf.org/doc/html/rfc5841 > It is hard for a TCP packet to discern higher moral quandaries like the meaning of life or what exactly defines 'evil' and from whose perspective such a characterization is being made. However, developers of TCP-based applications MAY choose to see some activities as evil when viewed through their particular lens of the world. At that point, they SHOULD mark packets as evil.
