A WebmasterWorld thread asks if Google penalizes or blacklists domains that are parked domains. A parked domain is a domain that has little to no content on it, that is basically a in limbo and is just sitting idle with possibly ads on them and not much more.
The majority of folks in the thread say that Google does not penalize a domain that is a parked domain. It may not rank well for reasons such as not having many links to the page or not having much content on the page, but for being a parked domain - that alone most likely will not penalize or blacklist the site.
In fact, Tedster said Google helps monetize parked domains with Domain Park. It is a Google AdSense product for parked domains. Domain park is a very controversial Google product, but that is for another debate.

I agree you can't penalise or blacklist something that isn't there, in theory its just a name thats being parked.

I agree with the majority that you have to forget about ranking for parked domains. Parked domains are useful if you have 500 or more domains

When you think of a good domain name, you buy it so later down the road you can create a site for it or sell it for a profit. It is a way to make money, so Google shouldn't penalize others for it. Besides, this is not blackhat at all.

Domain Parking is really good for some reason. It will give you security that before start your own business you can get domain name of your business so nobody will get this domain name from you. netfirms coupon
