We need to use Unicode steganography to hide the message "this smartwatch sucks" into an innocent-looking review.
How does this help anyone?
The suggestion is that negative reviews are suppressed. Communicating a negative review through a facially positive review would help avoid that.
But this is a negative review that is literally not hidden, to the extent that it is being discussed openly on a site about a completely unrelated topic.
Apparently something similar is used by Chinese customers reviewing restaurants. They would make a food sign from food pieces that spells "crap food" in slang, but otherwise leave a stellar review for the restaurant.
It sounds like they're hesitant to leave a bad review, why is that?
I had a review removed on Amazon for mentioning that the company bribed me for a fake positive review.
