Glad Kobo removed it, but I wonder if you'll have better luck getting Cottingham's whole account removed via Kobo's customer service than Rakuten's general press office. Cottingham is also using Kobo Plus (equivalent to Kindle Unlimited except it actually has a lot of high quality books) to get paid for free downloads of his spammy fake summaries, so perhaps you can report his misuse of that service as well.
