Why does bongacams work through tor?

Question

Tor

Tested several video chats on Tor. I launched all sorts of chat roulettes, video dating, etc. None of the services worked. Required either WebRtc or flash. None other than video chat for adult bongacams. Didn't even ask to turn on flash or anything else. Everything worked right away. How? After all, both flash and webrtc are disabled in the torus.
