Google has been sending detailed warnings to webmasters when there is the suspicion of spam content on the site.
Google has been really strict about cloaking and lately has sent out some general warnings that it would be even stricter in 2011. It appears that they are being as good as their word.
Barry Schwartz of Search Engine Roundtable shared some new warnings that some webmasters received in their account. This one below deals with cloaking, a subject Google is particularly vocal about.
Dear site owner or webmaster of bfenthusiasts.com,
While we were indexing your webpages, we detected that some of your pages were using techniques that are outside our quality guidelines, which can be found here: http://www.google.com/support/webmas…er=35769&hl=en. This appears to be because your site has been modified by a third party. Typically, the offending party gains access to an insecure directory that has open permissions. Many times, they will upload files or modify existing ones, which then show up as spam in our index.
We detected cloaking on your site and suspect this is the cause. For example at http://forums.bfenthusiasts.com/ we found:

In order to preserve the quality of our search engine, pages from bfenthusiasts.com are scheduled to be removed temporarily from our search results for at least 30 days.
We would prefer to keep your pages in Google’s index. If you wish to be reconsidered, please correct or remove all pages (may not be limited to the examples provided) that are outside our quality guidelines. One potential remedy is to contact your web host technical support for assistance. For more information about security for webmasters, see http://googlewebmastercentral.blogsp…-now-what.html. When such changes have been made, please visit https://www.google.com/webmasters/to…deration?hl=en to learn more and submit your site for reconsideration.
Sincerely, Google Search Quality Team

Webmasters who practice cloaking would have to watch out. Google seems to be on the war path. Do you use cloaking and have you received any mail like the one above from Google?
