There's an informative James Hoffman video about this.
Fraud is briefly discussed in the wikipedia page, but from the video, he's able to estimate that 75%+ of the coffee sold as kopi luwak isn't kopi luwak at all, it's just normal, cheaper coffee marked up a ton.
And of course, the remaining <25% that is real kopi luwak is ripe with civet abuse.
So please don't drink this coffee. If you're that interested in gut-processed coffee, do it yourself like that guy in Portland (but I still wouldn't recommend it).
