If the big concern is about sharing information, I think we could add another dose or reality to help with this. There could be an "error factor" in the scouting, so that each scout may have a slightly different take on the same players, so this way maybe it's not always easy to identify the players. And maybe the accuracy of the scouting report could be based on how good the scout is (which would be a new staff position). In real life, scouting reports are not going to be perfect, so maybe this is the way out of this sharing information issue.
Or, maybe sharing information isn't such a bad thing. Developing relationships with other teams in one's league is part of the game. Teams plan mutual TIEs, give tips about how to set lineup against other teams, etc. BB is a community, so I wouldn't worry too much about information sharing, especially since it probably won't happen all that much, and where it does it would be part of making a stronger BB community.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
