I think that archive links should be made to include a cryptographic hash of the file; this can prevent alteration of content (including of the original file that it is copied from) but also can allow alternative sources of the file to be found (or verified to be correct) according to the hash. (If someone is concerned they want their username removed, they could perhaps edit their copy of the file first and then archive it, although they should have someone to trust if it matches the original one or not, if it has been modified in this way (or any other way, e.g. removing some scripts and CSS etc).)
