> For example, a product gets a lot of 5 star reviews stating that the buyer bought it for their child/relative/friend and they are just sure that they will love it... 5 stars! Or "I just got this delivered yesterday and I haven't used it yet but it looks really great!"... 5 stars.

That doesn’t sound necessarily fake, that just sounds like humans being humans. You see this in many reviews on other sites, as well.

Not saying they’re not fake, but my understanding was that the fake reviews usually go through a little more effort than that.
