Amazon has a huge fake ebook problem as well.
I recently spent $2 buying an ebook that is still copyrighted. It is cheaper than the first item in search result that has more reviews. I thought, it's an ebook, what could go wrong.
Upon opening it, I found that the formatting is completely off. Words are concatenated. It was impossible to read.
A few days later, I noticed that the book is gone from Amazon store. I cannot open the link from my order page, and I cannot even ask for a refund. I had to ask customer service to do that. I guess this was a pirated book that was taken down.
It was a shame Amazon did not even notify me of this.
And I hope this doesn't happen on kobo or elsewhere.
That said, I've found at least one typo in every ebook I've read, even _Dune_ which I didn't get around to buying until it had been available in the Kindle store for _years_ ("pogrom" was mis-rendered as "program" and there was a formatting error in the glossary). I've been reporting all them using the interface, but not sure if they ever get fixed...
That said, it's not limited to electronic texts --- my second printing of J.R.R. Tolkien's _The Fall of Arthur_ also had a typo in it, but at least for that I was able to reach an editor at the publishing house who assured me that it would be corrected in later printings.
