I refer to the irritating practice an app automatically tweeting a
viral message from your account when you authenticate. e.g. "I just
got 50% somethingfactor on somelameapp.com, what's yours?"
of a warning message, e.g. "logging in will send a tweet from your
account" - best practice would be an opt-in checkbox or some such UI.
There needs to be a way for applications to be reported for doing this.
