SE has stated they will use 3rd party evidence to ban people in the recent updates.
That being said if a stream gets enough of a profile and is cheating/uses 3rd party tools SE will take note.

That being said 100 people watching the last stream I saw someone setting up ACT to customizer their bars isn't worth banning over because it's bring in views.
Now if you saw someone with 2k views SE may start taking note.
