Contrary to what Google says about the manual action "pure spam ," there was no auto-generated nonsense, cloaking, or copied content on my poor blog—just a few sponsored posts mixed in with storyline posts.
Unfortunately, I never managed to get the page back on Google before I closed it down—but maybe you'll have better luck!
How to remove the penalty
The only way out of this dark hole is to try to understand why Google classified your website as " chinese overseas british database pure spam," especially if—as was the case with my character blog—that really isn't the case.
A Google reviewer may have mistakenly considered your site to be spam and not helpful to Google users, or the issue could have originated with a previous owner of the domain (try Archive.org to check the page history).
SEO expert Marie Haynes suggests you start by cleaning up your website inside and out, removing any auto-generated content, scraped content, and black hat signals, and adding more value (e.g., creating new content that actually helps your target users).
Thin content is all that content where the amount of text is minimal and often not helpful to the user who comes to your site to find a solution to their problem.
