Wikipedia cannot regulate behavior in media not under the control of the Wikimedia Foundation, but personal attacks made elsewhere create doubt about the good faith of an editor's on-wiki actions. Posting personal attacks or defamation off-Wikipedia is harmful to the community and to an editor's relationship with it, especially when such attacks take the form of violating an editor's privacy. Such attacks can be regarded as aggravating factors by administrators and are admissible evidence in the dispute-resolution process, including Arbitration cases.
Linking to off-site harassment, attacks, or privacy violations against persons who edit Wikipedia for the purpose of attacking another person who edits Wikipedia is never acceptable. Attacking, harassing, or violating the privacy of any person who edits Wikipedia through the posting of external links is not permitted. ''Harassment in this context may include but is not limited to linking to offsite personal attacks, privacy violations, and/or threats of physical violence.'' This is not to be confused with legitimate critique. Inclusion of links in articles is a matter for sound editorial judgment.
