In case like this, I would not mind the IP blocking. These comments ain't "freedom of speech", thoughtful coversations, just having a different opinion, these are nothing, but comments of racism and hate speech. That's harmful speech. I highly doubt the IP blocking would happen, but I would not object to it in this case.I'm not a fan of review bombing, but I don't believe there's any justifcation for blocking IPs over it.
