Adult Content Not Allowed on Vaughnlive.TV?

Just some simple observations I made.I have zero clue as to what the Vaughn family consider "adult content".Since April 2013,I have noticed a great deal of adult content that was actually APART of Vaughnlive.tv.
Here's a list:

1. (kitten)
2. !sexytime
3. !feelup
4. !frenchkiss
5. (moon)
6. !assslap
7. !Bibigirl
8. !Wabbit
9. !bitchslap
10. !bobs
11. !cucumber
12. !eatme
13. !fagina
14. !poke
15. !vagina
16. (t2mjump)

Never mind all the casters who flashed parts of their private anatomy.The owners can't be responsible for the actions of the casters unless they encourage or support it (Bishh,RealmanPWNS,MeNellie,etc).

So what IS the definition of adult content on Vaughnlive.tv?
