Google has a blacklist. On this website type in your url and you will get the results immediately. Good luck!

Google, Bing and Yahoo search engines, use a variety of methods to determine which pages are displayed first the results. Their exact formula is a secret, but there are a few things you can do to improve your positioning. The term for this is Search Engine Optimization (SEO).

The worst penalty, being completely removed from the search index can be verified by the search, site:yourdomain.com

More commonly the search result position of individual pages of a site will dropped from previous rankings, as a rule pages and not sites get penalized.

Sites registered with Google webmaster tools would probably receive some warning emails along the way.

Google only updates page rank about 5 times a year, so any effect may not show up for a while, it seems to be tied to backlinks and might not effected by penalties in the same way.

If by penalized you mean removed from Google search engine results, then just enter this query in the search box: site:yourwebsite.com . If you are nowhere to be found, then your site have been deindexed.

If by penalized you mean they drop your ranking, you are no longer ranking for the keyword you were ranking for and you are nowhere to be found in the top 100, then you should check the latest google algorithm or update to check which rules that you might be breaking.

Google sends site penalization message to your google webmaster account.

If its been penalized there will be a reason for it. If it has a PR1 it probably means it is retaining that PR from a previous time it was listed. There are always way back from this though. Give me some details and lets see what can be done.
