However, even ignoring the monumental clue of the post which it followed, the simple phrase damnatio memoriae ought to be readily understandable by anyone who speaks English and has a modicum of intelligence, something I presumed was a prerequisite in order to participate in a serious debate forum.
We have a fairly well evolved language of our own without having to resort to an inadequate extinct language which translates words such as "Hades" into "infernus", thus starting the whole myth that the dead go to a fiery hell and burn forever in an "inferno". Nope, if you want to say something, it's better and easier to use the native language where possible. Latin is probably near the bottom of my list of languages to learn before I die. Yes, we can look them up, but we have already seen what "looking things up" can result in.
