Graffiti with legal paperwork: changing a website's face without its consent.

means The act of damaging or spoiling the surface or appearance of something — a wall, a statue, a website — usually by marking, altering, or vandalizing it without permission.

from Built from 'de-' (undoing, removal) plus 'face,' rooted in Latin 'facies' meaning appearance or form. To deface, literally, is to strip something of its face — its presentable surface — leaving only the damage behind. The word has carried that same sense since it entered English centuries ago for vandalized monuments and documents, long before it got a second life describing hacked websites.
