As for the technically minded, we get to see all of these spam messages from the rouge applications whenever one of our friends add them.

A simple solution as I see it, is not to enforce full vetting of all applications, but to simply change the notification system so that it becomes blatantly obvious when messages are not genuinely from a friend initiated action, but from some application attempting to masquerade. I do support stricter control over applications, but perhaps an interim measure would be to modify the notification display.

The notification system allows too much flexibility over the format of the messages sent out, for those interested, this is what the Error Check System and Closing Down notifications look like.
