You know where this RFC attitude brought us - Web browsers accepting
broken HTML, resulting in sloppy non-standard pages that display in
less than average of the browsers. Especially when it comes to
security, e.g. firewalls, it's better to turn the RFC quote:
Be conservative in what you accept and be
liberal in what you do.

Meaning: block all network packets that could potentially be harm and
pro-actively try to stop any spammer using non-compliant probing
techniques.
