In the past, we have had users who have been emotionally damaged by personal attacks, and we've also had some users who've threatened to commit suicide because of them. The prohibition against personal attacks applies equally to all MicroWikians. It is as unacceptable to attack a user with a history of foolish or boorish behaviour, or one who has been blocked, banned, or otherwise sanctioned, as it is to attack any other user. MicroWiki encourages a civil community: people make mistakes, but they are encouraged to learn from them and change their ways. Personal attacks are contrary to this spirit and damaging to the work of building an encyclopedia.
