Whats this crap now.
All ads are getting rejected because they don't have a call to action. I can't get anything through unless it says 'Register now! or Click here!'
While previously (24 hours ago) this was never an issue.
You should always have a call to action anyway.
I think they are requiring it so that people don't buy traffic then wonder why their ctr is 75% less than what it would be with a call to action.
