You can fight spam in referata using the "Site settings/Privacy/Anti-spam" feature. I added the question "What is the largest wiki encyclopedia?" and answer "wikipedia" to WikiPapers, and no more spambots.
2012/3/16 Chitu Okoli <Chitu.Okoli@concordia.ca>Hi everyone,
As I mentioned in an e-mail last week, we are on the final stages of a large literature review on scholarly research on Wikipedia. We have extracted and organized most of the data and have published it to a Semantic MediaWiki wiki at http://wikilit.refarata.com. [Thanks to emijpr for inspiring the structure through WikiPapers.] As I indicated, this is sort of an incubator site to finish up our data to prepare for publication, after which we intend to export the data permanently to other sites like AcaWiki and WikiPapers.I will be happy to help you to import papers to WikiPapers when you want.Good luck with your literature review.
