Has anyone come up with a quick method for detecting if a domain
name is parked, but is not being used except displaying ads?


I don't think it is possible: "being parked" cannot be defined in an
algorithmic way. My own domain sources.org does not even have a Web
site (and I swear it is not parked).

Let's try:

* Bayesian filtering on the content of the Web page, after suitable
  training?

* Number of different pages on the site (if n == 1 then the domain is
  parked)?

* (Based on the analysis of many sites, not just one) Content of the
  page "almost" identical to the content of many other pages? (Caveat:
  the Apache default installation page...)

Dont forget there are mail only domains. I used to have one. Now it is used to forward html somehow to my real homepage.
