Amazon competitor got our belt listing taken down by saying it contains drugs
Similar thing happened to me. I built an online Japanese - English dictionary and used AdSense to monetize it. One day I got an email saying that my domain has been permabanned because my website appears to be promoting rape and pedophilia. As an example of one of the many offending pages on my domain they sent me urls to the definition and translation of words "pedophilia" and "rape" in Japanese.Of course none of my competitors using the exact same data set had any such problems.I tried for YEARS to appeal it. There are simply no humans working at Google and nobody reads your emails.Edit: Actually, I did get a response a couple times but it was obviously automated. They just said to remove the ads from the pages where such words are displayed. So I added a simple rule and a column in the database to hide ads for those keywords. That just triggered the bot to move down the list of their "obscene" language. Next it was the names of various sexual positions, acts and fetishes (Japanese does have a very rich vocabulary in that topic), then manga slang, even silly sounding onomatopoeias that when explained in plain English are "vulgar", etc.. It seems once your website is flagged there is simply no way get clean.
