The feed is indeed online and streaming ambient audio from the computer's microphone. I sent a problem report and PM to the feed provider as well as a TOS violation report to Broadcastify administration.
I have seen this happen many times in the past. I don't know if this provider was one of them, only the admins would know.
I can't believe people would put up a feed and not at least listen to it, or intentionally broadcast their personal life to the worldwide internet.
Maybe he is intentionally bugging his own home for some reason, checking up on his wife, etc.
These types of violations can be reported at the link below:
