I also received the same email message.

Last week several of my campaigns that had been running for years had all their keywords drop to a quality score of 1. No explanation, no notice, nothing.

I also have been using Adwords since 2002 without any major problems. It baffles me that out of the blue I am threatened with being banned for quality problems - when nothing has changed.
