Just look for the copied artwork. It's pretty simple, really.
You're conflating several things, imho, which are important to note.
Firstly, not everyone is entitled to voice their experiences publicly, it depends on where one lives, and what legal precedents there are. For the avoidance of any doubt, even in a country such as the USA there are limits to voicing one's experiences (such as when a judge issues a gag order).
Secondly, fake experiences are extremely likely, and in fact, have been common for at least one generation (20 years) on the Internet. Businesses use fake reviews to hurt competitors all the time. Businesses also use fake reviews to mislead customers. Individuals with an axe to grind do it all the time, too.
Historically speaking, the original justification by Google and Facebook for requiring real identities in the late 2000s was precisely as a silver bullet proposal to fight anonymous fake reviews, which were causing real damage to real businesses and people.
Thirdly, user reviews are simply a bad idea. The system suffers from all sorts of statistical biases, including survivorship bias, self selection bias, payola, etc.
The idea itself of a review, ie a critical account from personal experience by someone you trust, is actually sound.
The Internet companies however do not offer sound reviews, they offer accounts that may or may not be critical from experiences that may or may not be made up by people whose identity may or may not be made up and whose motives you may or may not want to trust. That is imho an accurate description of user reviews. Allowing deliberate anonymity only compounds the problems.
