Dear site owner or webmaster of [url removed],
While we were indexing your webpages, we detected that some of your pages were using techniques that were outside our quality guidelines, which can be found here: [link]
In order to preserve the quality of our search engine, we have temporarily removed some webpages from our search results. Currently pages from [url removed] are scheduled to be removed for at least 30 days.
We would prefer to have your pages in Google’s index. If you wish to be reincluded, please correct or remove all pages that are outside our quality guidelines. When you are ready, please submit a reinclusion request at [link]
You can select “I’m a webmaster inquiring about my website” and then “Why my site disappeared from the search results or dropped in ranking,” click Continue, and then make sure to type “Reinclusion Request” in the Subject: line of the resulting form.
