To be fair, a mate of mine had 'Incident Reponse' in his professional signature for more than a month. At least the Cyber Analyst part was spelled correctly I guess?
Incident reponse is not that bad of a typo hell it has roughly the same meaning. Reponse meaning to answer in French, so incident reponse would mean the same thing as incident response. Mind you thats cause we get responses from Norman French but hey it works.
