Sometimes, a misplaced post isn't abuse, or might even not be an absolute case of right or wrong, but might be a case where a post could be or should be moved. However, assuming a reply has happened, there isn't a direct way to either delete the post
or draw the moderator's attention to the post other than "Report as abuse".
For example, I posted a post in the Networking forum (http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/82d59124-c4bb-46bd-8f62-2c53b5a47026) on the recommendation of another MVP over on answers.microsoft.com, by clicking a hyperlink
and not quite paying enough attention. A little too late (after someone replied, thereby blocking me from deleting), I saw where my post would have been better placed over in the "User Interface" forum. But other than posting here, which is somewhat
indirect, I don't have a direct way of communicating with a moderator.
So, if anyone would like to move it for me, please move to the Windows 7 User Interface forum.
And if I were in charge, I'd change "Mark as abuse" to say "Flag message for moderator review", and I'd add "Posted to incorrect forum" as one of the choices. The kinder gentler wording would still allow for turning in evil-doers, yet also support
the less severe act of simply asking a moderator to take a look at a post.
