I have found now this paper that seems relevant to this conversation:
Forte, Andrea, Nazanin Andalibi, and Rachel Greenstadt "Privacy, anonymity, and perceived risk in open collaboration: a study of Tor users and Wikipedians." Proceedings of Computer-Supported Cooperative Work and Social Computing (CSCW). Portland, OR. CSCW 17 (2017): 12. http://andreaforte.net/ForteCSCW17-Anonymity.pdf
