I thought cams are Stephen Burke's doing. Because,
The only reason for Burke to install cameras would be as blackmail material for the prostitution ring and the donors. However, it makes 0% sense for those liaisons to occur on a college campus ... so, I doubt the cameras are the direct doing of Burke.
I've heard some say it's the Betas - from a 'tech' standpoint I can see that, and from a 'revenge of the nerds' standpoint I can see them sending pictures out, but the link between the Betas and Burke has not been established.
Others say the obvious choice is Vinny or an associate. However, that doesn't make much sense to me. Why would he send pictures to Chad? That makes even less sense than the Betas.
Probably not Quinn either. She likes to think she is a mastermind, but has shown time and again that she's terrible at her business (losing money, losing drugs, not being able to keep the restaurant secret, etc.).
Maybe it's that bastard Luis creeping on college kids whenever he installs windows, which apparently needs to be done frequently with all those dildos flying around ...
