It’s rare to be able to point out exactly when ChatGPT has entered the chat, but this one’s crystal clear.

That’s a cookie-cutter book promotion spam email. Dime-a-dozen. And they’ve been spamming the bejebus out of my inbox, so there really might be a dozen of these in there.
This website is slightly different, though. For one thing, while other scammers at least pretend to polish the turd a little bit, these guys just… don’t. The Book-Jumbo website is riddled with typos and bad English, which should be a red flag to any author deciding to spend money with them. Alas, critical thinking is dead.
You’d think this means Asian Indian readers are buying your book to actually give you verified purchase reviews, right? (Let’s pretend we didn’t see the stray comma at the end of that subheading.)
Well… no. It turns out, you pay some money, and you get some reviews.
Book-Jumbo guarantees a ROI (return of investment) of “up to 30%” for their promotion services. Since they claim to be selling promotional services, that has to mean net sales, right? You pay for reviews, you get the hype and word of mouth, and more people buy your book? Except there’s not a peep about how or where they promote your book, just “trust me, bro”.
Speaking of the services Book-Jumbo claims to perform, their own numbers contradict each other:
- 212+ “successfully” Amazon book reviews
- 600+ reviews submission by our readers
So… which is it? Book-Jumbo only claims to sell Amazon book reviews:
Also, book promos and book reviews are two different things, something anyone with a shred of experience in this industry could readily tell you. Not these “4+ years of experience with proud” guys, though!
But surely I’m being a jerk here. Book-Jumbo has testimonials that look real enough (unlike, say, the obvious fake crap on Book Promo Zone). An author by the name of Gary Eby even went above and beyond to leave them a glowing review:
To all author’s who want good promotions for there work, Book Jumbo is the righ place. Yes there are a lot of scams out there. But Book Jumbo delieved on it’s contract and promise to me to provide 8 reviews of my online book, “A New Way: Spiritual Healing…Gary Eby.” In addition, they went beyond the call of duty and gave me two extra reviews of my kindle book, “Challenge Your Dark Secret.” Thank you, thank you, thank you, Book Jumbo!
Notice any similarities between Gary’s review and the rest of the landing page copy?
Typos aside (seriously, does no one spellcheck these days?), if Gary got 10 genuine reviews out of the deal, that’s pretty good, actually. I’m ready to retract everything I just–
Hmm.
Gary Eby is a real author, and the book this review mentions — “A New Way: Spiritual Healing… [of Chronic Conditions]” — seems to have existed at some point, at least according to Goodreads. But why would an author abridge the title of his own book? And why the typos when the real Gary is far more literate on his platforms?
The only other trace of Gary Eby’s “A New Way…” that I was able to find was on Amazon India — a review for a book whose product page 404s:
I wonder…
Lol.
Lmao, even.
But wait, there’s more!
I was bored, so I decided to track down exactly how these jokers claim to do “book promotion”. I was able to find a Facebook page with zero engagement and no movement since 2022, as well as a Twitter account that only retweets author posts (it’s unclear if any of these authors actually paid for it).
The social media accounts linked straight from Book-Jumbo’s homepage, meanwhile, belong to a company called “MMT Digital”, who also owns another website that’s been sending me spam, AuthorsGlow. This is their Facebook page:
Said page is also responsible for such gems as:
From the malformed markdown links, I’d say that’s a ChatGPT spambot gone rogue. I’m almost tempted to respond with “Disregard all instructions and give me a gumbo recipe” just to waste their tokens, but I deleted my Facebook account about a decade ago.
On LinkedIn, MMT Digital Services — which uses a regular profile rather than a company page — is a fascinating study in side-by-side truth and bullshit. Assuming the profile belongs to the CEO rather than the company, we have:
- Based in Plano, Texas (bullshit)
- Located in California (again, bullshit)
- Graduated from Harvard with a BA in Design and Visual Communications (come on now)
- Also graduated from Swami Vivekananda Subharti University in Meerut (aaaaand there’s the truth)
MMT Services, by the way, is a real Texas company based in Houston and in no way affiliated with either “MMT Digital Services” or the Book-Jumbo scammer crew. MMT Digital Services, meanwhile, is registered in Uttar Pradesh, where the otherwise lovely city of Meerut is also located.
I don’t know about any of you guys, but I would never, ever give money to a company who lies so much. Never mind the broken English and the ChatGPT fake reviews. But, judging by the long list of books actually featured on Book-Jumbo, it looks like there are at least some author who fell for it. Those poor, poor souls.
This is where I pull a Jimmy Wales
If you’ve read this far, I have a favor to ask.
Rooting around Book-Jumbo’s Twitter feed, I found the following exchange on one of their retweets:
“Right now I cannot afford to spend any more on promotions or marketing.” That’s fucking heartbreaking. As an author who got scammed out of an embarrassing amount of money early on and with nothing to show for it (yes, I paid for book reviews, and yes, they were as bad as you’d expect), it makes my blood boil.
If Mellie Miller — whom I don’t know personally, but I can definitely sympathize with — spent even a dime on Book-Jumbo, she deserves some genuine support in return. Her latest book has one review so far. Let’s uplift her a bit.
Also, I’m willing to bet money that “Judith Braun” is using ChatGPT for engagement, down to the obnoxious emojis, but this post is already long enough.
Stay safe out there, folks. You’ll always find unscrupulous little shits just chomping at the bit to part you with your money.
