Since this was asked, Smoke Detector (“Smokey”) has started running on SE. Smoke Detector is a bot (run by Good People™ who work closely with SE staff, and some of whom are mods) that watches Stack Exchange for exactly these kinds of things. The bot doesn't have enough reputation on Stack Exchange to auto-flag these posts, though.
However, a relatively new feature of Smokey allows users to sign up to voluntarily delegate their flagging privilege to Smoke Detector, which gives Smokey a secure token from your RPG.se account so that it can flag as if it were you on RPG.se.
There are limitations built into Smokey to prevent this delegated flagging permission from being a problem, and past accuracy is in the 99.9% range, but technically the responsibility for an account's flagging behaviour still lies with the owner of the account, not with Smokey. Obviously not everyone is going to be super-OK with a bot having that kind of permission on their account, so it's necessarily extremely voluntary. It's for those who have faith in this kind of technology and want to volunteer to help out.
To learn more about Smokey, visit the bot's homepage and the wiki page on the Autoflagging feature. You can also talk to helpful humans about Smokey and see the bot in action in the Charcoal HQ chat room.
This doesn't merit marking this feature request status-completed since Smokey is more of an external tool or workaround. Perhaps something like Smokey will be built into SE some day and this can be marked completed, planned, deferred, or somesuch.
