I wrote a one star review and posted pictures of a badly burnt pizza served at a restaurant in Berlin.
Google sent me an email telling me they removed that because the restaurant filed a defamation claim
Sounds similar to Nintendo dmca takedowns. You could challenge the defamation claim in court and win, but you would have to spend a lot of money and time, and the only thing you get back in the end is the right to post the review.
You could challenge the *DCMA* claim in court and win, but you would have to spend a lot of money and time, and the only thing you get back in the end is the right to post the *code to Github*.
I gave a one star review to some cheap restaurant in Potsdam 10 years ago. I literally just said you get what you pay for. Last year I got a similar email from Google saying the review was removed for defamation.
