Can I stop iPhone apps from changing my Gmail status?

I recently got the Mo+ GV iPhone app to replace talkatone and it's a thousand times better. The problem is is that when I'm logged in (It connects to GTalk/voice) my gmail status is changed to an annoying ad. something like "I'm using Mo+ get it now at blah blah", and I know a lot of other apps do this too. Is there a way to disable this from happening? (Its not in the app settings)
