|This page in a nutshell: Comment on content, not the contributors. Users that make ad hominem attacks may face blocking and banning.
Do not make personal attacks anywhere on Wikipedia. Comment on content, not on the contributor. Personal attacks harm the Wikipedia community and the collaborative atmosphere needed to create a good encyclopedia. Derogatory comments about other editors may be removed by any editor. Repeated or egregious personal attacks may lead to sanctions including blocks or even bans.
