Thryduulf is one of the members of Wikipedia's 2015 Arbitration Committee who banned our editor Coat of Many Colours following a complaint by the Wikipedia editor Hafspajen that Coat was hacking Hafspajen's computer. Hafspajen later claimed that it was Wikipedia itself that was hacking her computer. The issue was investigated by Wikipedia and no evidence was found to suggest that Hafspajen's account had been compromised. Hafspajen nevertheless continued to maintain that Wikipedia was hacking her computer and ceased editing at the beginning of the year (2016).

Thryduulf doesn't self-identify on his user page but he does identify as Chris McKenna on an alternativ e account he used when employed by the Wikimedia Foundation to deliver the 2014 Wikimania London event.

Thryduulf (Chris McKenna)

Thryduulf became an administrator in 2005 and an arbitrator in the 2014 elections. He sought relection in 2016, but failed. 

Edit stats conducted mid-May2016 show that Thryduulf has made some 55,000 edits over a twelve year period commencing 2004, averaging some 13 edits a day. Of these, some 24% were in article space. His editing interests appear to be especially railways and nudism.

Thryduulf has been very heavily criticized at Wikipediocracy for his defense of Commons images of questionable taste and value. For example, he defended the notorious "Stan Spanker"images
