Big scary Goodreads scammers - why you shouldn't trust paid "reviewers" from Goodreads

Do you get tons of spam about book reviews too? Some "Mary", "Cheryl" and others began to spam my mailbox so I had a nice idea to have some fun in my boring life. Whenever they send me anyhitng, I just respond "yes but only if it's free." Usually they shut up, but I got this one day: Scary, right? Well, not exactly, because when I blocked the sender, I didn't get any new mails like this. How am I supposed to believe in their hacker skills if they can't ever spam me to death properly? Lol This is their "website": https://cherylreviews65.wordpress.com
