So I've been reviewing for quite a while. Close to everything in my dorm room is free. From my pillow to my bedding to my chair to my speakers etc. It's great, however it is time consuming.
I stopped somewhere around a half a year ago for because Amazon started being not makpid shutting down threatening lawsuits etc. At that point, I felt it's just not worth it.
The way amazon knows it's fake is off a few things.
1 if the products was bought with gc on many occasions.
2 constantly posting long reviews without good reason.
3 exaggeration
4 activity.
Those are the ones I know about.
They've actually gotten pretty good on a few of the chats I'm on, ppl have gotten shut down. So be careful! Enjoy!
