I'm active at WP:AE, the arbitration enforcement noticeboard. This is a FAQ in which I try to answer questions that occasionally come up.
Please make a report about it at WP:AE in the form recommended there with all required information. Sorry for the hassle, but this ensures that we have all information we need to be able to act on your request and that the other user has an opportunity to respond to the request.
If you received a message like this one, you don't need to do anything. This is an informative message that any editor who is active in certain topic areas may receive. It is to inform you that that there are heightened expectations about user conduct regarding editing in such topic areas. The message doesn't mean that you did anything wrong, or that you are about to be blocked or banned. You may still want to read the pages it links to, though.
Are you the editor who I banned or blocked?
It isn't. The arbitration process is intended to result in binding solutions to conduct problems in circumstances where the normal consensus-based dispute resolution processes no longer work. That's why the Arbitration Committee has established rules for arbitration enforcement that make clear that "administrators do not need explicit consensus to enforce arbitration decisions and can always act unilaterally." They are encouraged, however, to seek input from other admins in unclear cases, and they may overrule a consensus of other admins, but only with caution.
Only if and when the sanctioned user makes an appeal does consensus come into play. The result of an appeal is dependent on consensus among the people reviewing the appeal, as described in the rules for appeals.
