There is no rule that is objective and not open to interpretation on what constitutes a personal attack as opposed to constructive discussion, but some types of comments are never acceptable:

These examples are not exhaustive. Insulting or disparaging an editor is a personal attack regardless of the manner in which it is done. When in doubt, comment on the article's content without referring to its contributor at all.

Personal attacks are disruptive. On article talk pages they tend to move the discussion away from the article and towards individuals. Such attacks tend to draw battle lines and make it more difficult for editors to work together.

Contributors often wish to have their viewpoints included in articles. Through reasoned debate, contributors can synthesize these views into a single article, and this creates a better, more neutral article for everyone. Every person who edits an article is part of the same larger community—we are all .

As a matter of polite and effective discourse, arguments should not be personalized. That is, they should be directed at content and actions rather than people.

When there are disagreements about content, referring to other editors is not always a personal attack. A posting that says "Your statement about X is wrong because of information at Y", or "The paragraph you inserted into the article looks like original research", is not a personal attack. However, "The statement..." or "The paragraph inserted..." is less likely to be misinterpreted as a personal attack because it avoids referring to the other editor in the second person. "The paragraph inserted here [DIFF] into the article looks like original research" is especially advantageous because the DIFF cuts down confusion. Similarly, discussion of a user's conduct or history is not in itself a personal attack when done in the appropriate forum for such discussion (for example, the other editor's talk page, or WP:Administrators' noticeboard/Incidents).

Editors should be civil and adhere to good when describing disagreements. The appropriate response to an inflammatory statement is to address the issues of content rather than to accuse the other person of violating this policy. Accusing someone of making personal attacks without providing a justification for your accusation is also considered a form of personal attack. (See also: Incivility.)
