Watchman of Doom transmissions
The Astros are using WoD to intercept Alliance transmissions. Presumably, if WoD was no longer useful, the Astros would dispose of him. The Alliance probably sends out junk broadcasts with misinformation so that the Astros will intercept them and waste their time chasing the false info. But if the Astros realise the Alliance is doing this, they might conclude that there's no point keeping WoD around, and terminate him. Therefore… the Alliance might be making a conscious choice to allow the Astros to intercept some broadcasts with actual locations containing personnel, which will mean a high chance of death for said personnel. Astros think they've scored a victory, and keep WoD around for a little longer.
And Titan TV might work out what's going on, and realise that he's slaughtering troops who are dying so he doesn't.
