My adwords account suddenly stopped displaying any ads about a year ago.

As I tackled the problem, my understanding grew that the Google's Adwords support staff didn't have any additional information than what was already published online. That kind of support is fine for maybe 50% of your users who don't read the online docs. Probably not of use to HN readers.

I suspect that Google doesn't provide information about recent changes to algorithms to the support staff that would help them understand what's going on. I can understand why they might not want to, but it reduces the quality of support that can be provided.
