All of the audios feeds on Broadcastify.com are provided by volunteers, each one using their own computer and scanner radio.

If a scanner feed goes offline (meaning we stopped receiving audio from the person that volunteered to provide it) and it remains offline for 3 weeks it's automatically removed from the directory.  This can happen if someone decides to stop providing the audio for a feed or if they're no longer able to do so (they could have moved out of the area, their computer/scanner radio died, etc).
