NOTE: this is an archive of my response to Tom Griffin of Wiley's email to the Liblicense listserv claiming that Wiley do not create fake DOIs. My response is below, in case it does not pass moderation at the original list.
I am the person who posted the original document about fake DOIs (https://docs.google.com/document/d/1uTVHPI8r4VO31KihsyiBHsh_gp8jZ38fMvP5nP5XOkw/).
Every single claim you make above is demonstrably false.
Wiley does not use fake DOIs.
Wiley does have fake DOIs on its website. I have attached a screenshot, and I refer you to this blog post: https://go-to-hellman.blogspot.co.ke/2016/06/wileys-fake-journal-of-constructive.html. To claim otherwise is creatively redefining 'fake DOI'. What you're doing is polluting the web with things that are designed to match the pattern of real, Crossref registered DOIs, but which are in fact designed to trigger access restriction.
In addition to creating fake DOIs, the blog post linked shows that Wiley is creating fake articles attributed to real institutions.
We strongly support the DOI system and were a founding member of CrossRef
Goeff Bilder at Crossref has explicitly said (here https://twitter.com/gbilder/status/736979917720702977) that Crossref discourages the behaviour you have exhibited. So whether you claim to support them or not, they don't support what you are doing.
What was contained in the document were URLs
The URLs in my original post were constructed by me using the pattern I observed on Wiley's site to reach a PDF directly from a Wiley DOI. That is, "http://onlinelibrary.wiley.com/doi/" + DOI + "/pdf". I found those DOIs in the wild and tried to resolve them via Wiley's website, as explained in the first link.
These URLs are not discoverable online, they cannot be indexed
Here's one being indexed on Google: https://www.google.com/search?safe=off&q=Constructive+Metaphysics+in+Theories+of+Continental+Drift&cad=h.
... and will not have an impact on the DOI system
The entire problem is that they are having an impact. If academics in the course of their work find an apparent Wiley DOI and try to visit the corresponding page, then find their institution blocked, that is a very serious and damaging impact.
Only individual IP addresses were affected, no institutions were banned from accessing Wiley content
After I initially visited the URLs corresponding to the fake DOIs in the first link, several departments and a separate institute at Cambridge were blocked from visiting Wiley, including open access titles. The block lasted at least a week.
All access has now been restored and clicking on those links will no longer disable access.
Here's a thread on Twitter demonstrating this to be false: https://twitter.com/CT_Bergstrom/status/745860745611591680
The URLs are a security measure visible only to Wiley and our customers’ security officers, and we do not know how they came to be known more widely.
See my first post and the google link above. They came to be known more widely because I posted about them after you blocked my institution.
I see only two possible explanations for your email: deliberate misinformation or complete technical incompetence. Either way, I hope the library community and the broader academic community will continue to hold Wiley accountable for their harmful behaviour.
