Linked? I dunno.
Do they talk to each other? I think that at least some do.
The last time I talked to someone on the AdSense Optimization Team, last fall, they went on with the usual, more bigger, ATF routine.
I asked if that might hurt my site in any way.
The answer was that it wouldn't hurt from an AdSense POV, but it might cause problems with the WebSpam Team.
So it seems that somehow at least some AdSenes staff are either talking to the spam team, or getting the message some other way.
