Information posted on diynot does not generally contain personal identifying information so there is no "data" to protect. Presumably freezing a user account and preventing use of the search facility is as far as the mods can or need to go. Removing contributions from posters would be difficult if not impossible, where people are qouted or involved in an ongoing discussion. That said the forum could do with clear guidance on what would be considered inappropriate comment or language.
