I think being cautious about any solution makes a lot of sense Robert especially considering the state of things.
Just an opinion as to any probable causes so that you have at least some kind path to travel to find a solution.
I did mention "Unnatural link patterns" which as you mention could equate to "We worked the PR angle really aggressively".....
Depends on how aggressively though and what was done and whether this is actually responsible for causing the problem....who knows without more data or analysis, just guessing.
