這兩篇都寫了幾個不錯的例子

Most reviews are protected under the First Amendment (free speech). However, a court can find a reviewer guilty of defaming a business if they post factually incorrect accusations. Freedom of speech typically boils down to whether someone is expressing their opinion or asserting a fact.
For example, if a customer says that you are a jerk or you “charge an arm and a leg,” you cannot sue for it (or, you will not win if you do sue).
But, if a customer claims that you are unlicensed or that you stole her watch while painting her house, you could have a case. A false statement of fact that hurts your business is not protected by the right to free speech.
And for all you avid reviewers out there, take note of this distinction. It’s important to choose your words carefully before bashing a business on a review site. Stick to opinions and truths.

所以不是說什麽都不需要證明，你說的是事實，但這種表達不能算“事實”。 比如這個：
Feb 19 2019 （日子錯了，今天才2019年1月23日）: The owner Michelle has no respect for people, she is nice to students and parents face to face, but behind their back she thinks they are crazy coming to this place, yes, she believes most of the students are just wasting time, she believes they wont improve, she just want your money! I have seen the the SAT mock test results for about 30 students there, after a few months' intense class and 3-4 mock tests, they have not improved at all, no one!
事實是，你其實不能代替另一個人的想法。
還有這個：Also they have a filthy refrigerator on the second floor, Michelle herself never put anything there, but she stores students snacks there and as long as the expiration date is not passed she would give the students milks no matter when it is opened.
事實是，你never看見而已。
這個是文章建議：
- The point of this article isn’t to scare you off writing honest, negative reviews online. There are thousands of negative reviews posted every day and only a very small number of them end up with lawyers involved. The big takeaways are:
- Only post things that are absolutely true.
- Make sure you’re expressing an opinion by saying things like, “I didn’t like X” rather than making statements that could be interpreted as facts like “X sucks”.
- Avoid accusing the companies you’re reviewing of criminal behaviour like robbing you, scamming you, and so on.
- Don’t write reviews while you’re angry. Wait a few days and see how you feel. If you still feel the need to write a negative review, do it carefully and deliberately.
- If you are sued or threatened with a lawsuit, contact a lawyer immediately. A few hundred dollars worth of legal advice now could save you hundreds of thousands of dollars in the future.
即使沒有官司，說話嚴謹，有理有據都是好習慣。
