Castor tells you that RedBlueAI were hired by a community of librarians calling themselves DeepLink Cooperative. 

One of the DeepLink Cooperative’s assistant AIs Itivillustay greets B@TB0!D v01ds33k0r in the guise of a pig. Itivillustay reveals that a number of the members of the community have outright disappeared. These disappearances happened shortly before RedBlueAI was engaged for contracted services.

It says, “They stopped logging in and all the links and information they preserved are likewise gone as if they never contributed to the DeepLink Cooperative at all. I remember their names, avatars and significant posts, but they are no longer part of the archive in any way.”

Option 1: Ask Itivillustay, “Is there a list of missing members as you recall them? Is there anything about them that was unusual or significant?” 

Option 2: Rough up Itivillustay to get them to share more than they might be letting on.

Option 3: Perform your own analysis of the DeepLink Cooperative system and archives (Intuit Architecture skill check).

Option 4: Use a program to probe the DeepLink Cooperative system.
