I've written about damnatio before, and the fact that it's regularly not understood correctly in the public imagination. Damnatio is not a systematic destruction of an individual's existence, it's the removal of credit from his public works and the erasure of his public honors. It does not prohibit people from talking about him, and to be truly effective the individual must continue to be spoken of as a very, very bad man, in Seinfeld terms. It is, after all, just as the name suggests condemnation of legacy, not erasure of identity. Indeed, kind of the point of damnatio is to ensure that anyone who reads an inscription that has suffered an erasure (the procedure is carried out almost exclusively, with very few exceptions, onlynon inscriptions) knows exactly who this person is, and epigraphic erasures often make sure you can actually read the name
