In the area of trademarks I believe, you need to demonstrate that you are not just "parking" the name but also actually taking actions to sell and market the product/service. A similar regulation should be applied for websites to ensure they are using it for the proposed purpose.
There is precedent for this in WIPO court (around abusing domain parking), but unfortunately the shady businesses that profit off of parking domains are getting smarter by auto-generating "specialty based news services" based on the keywords in the URL instead of throwing up exclusively ads. Take for example, the World News Network which squats domains with pages like "http://policearrest.com/. (See an example WIPO proceeding here http://www.wipo.int/amc/en/domains/decisions/html/2005/d2005...)
World New Network had squatted a domain that we were interested in (a gobbledegook web 2.0 name, mind you), and they wanted 80k under the idea that this website was an important part of their news operation. If this was an English word it might make sense, but it was far from it so the whole game reeked of extortion (in the casual, not legal, sense).
