The "weakened site" theory makes a lot of sense - Matt also blogged about that in relation to proxy server hijacks. Restoring trust can be a difficult job, especially if you aren't clear about how the loss of trust came about. But especially in cases like the -30, removal almost takes a manual action. The algo will not remove it automatically once it's in place.
