For instance, a guideline could follow this syntax: "As opposed to verbally abusing another poster, address his or her point of view and provide your own in a friendly, nonabrasive manner". That is absolutely acceptable and doable, I believe.
The staff should revise this to the following: "be respectful of one another when discussing topics relating to XYZ". Let's attack the problem at its source and provide a more explicit outline of conduct.
But that's already been the 'posting guidelines' since forever.
- Insults and personal attacks on other members will not be tolerated.
- Offensive language is allowed but should be avoided and never directed in the form of an attack towards another member.
- Do not start a topic that condones illegal activities or activities that tend to incite flame wars, such as: drug use, killing, warez, theft, race, nationality, sex, and religion.
- People engaging in abusive activities will have their accounts rendered inaccessible and be permanently banned from GameDev.net. Furthermore, if necessary, we will take whatever steps are needed to report you to your ISP for abuse, and won't hesitate to contact law enforcement authorities should the nature of the abuse warrant it.
Sure, your text could be appended to the back of "Insults and personal attacks on other members will not be tolerated.", but that's really already covered by the rules, so I don't see how it'd actually help.
