AIs and Antags, how much silence?

[Grek]

I proactively direct people to Blobs, Syndicates, Wraiths, people trying to enter the AI Upload (Even the Captain gets a "Hello, Captain.") and antagonists who are being dickish to the AI. I announce Changelings, Wizards, Vampires and loud Traitors once and then shut up about them until ordered otherwise. For quiet traitors, I am equally likely to PDA them that their actions are very rude, or print off a description of their actions on the Security printer without informing Sec.
