See http://impactstory.org/collection/lesb5u and look at some of the highly discussed items you'll see something pop up in the Facebook numbers, specifically that for five items the facebook comments, likes, and shares all have exactly the same numbers (124, 396, 245 respectively)....In the collection c2sljf the exact same numbers pop up. Is this just what Facebook reports when it maxes out or something?

The tiids are:

Thanks to some detective work from @mfenner and @cameronneylon, the problem is more clear now:

FB is resolving DOI links. Some of these resolve to article pages that require cookies. When the pages see that the FB server doesn't have cookies enabled, it redirects to a "you need cookies" page. Taylor & Francis and NEJM DOIs (potentially among others) seem affected. See #109 for more on this.

So, for this set of DOI links, FB thinks they are all synonyms for a few "you need cookies" pages, and that lots of people are linking to those "you need cookies" pages.

It is not clear how to fix this, other than blacklisting DOI prefixes we know are troublesome (returning NA's from them).
