I hate that "review bombing" has come to be considered a bad thing. It's not always for a great reason, but it often is, and it's one of the most prominent ways normal people have to make their voice heard against large companies. That's obviously also the reason it's been put down so much, but it sucks.
Google will automatically remove reviews they consider brigading or review bombing. The same thing happens when a business blows up for some bad press online and people review bomb them on Maps. When you go back and check after a few days it’s back to the way it was before.
