While subjects such as the global south and notable women are inevitably sidelined, organisers Cameron and Cobb have previously drawn in more than 60 would-be Wikipedians at a time during arms industry wikithons in Manchester and London.
Two dozen volunteers gathered in a classroom in central London last week for an in-person Wikipedia editing event known as a wikithon, fueled by free servings of vegan Ethiopian food.
Cobb spoke of a sense of wonder when people realise how easy it is to actually contribute, noting that the experience alone is quite empowering for people while attenders maintain respect for Wikipedia's commitment to rigour and quality control.
The main goal of the arms industry wikithon was to pull together publicly available information from other sources into one place. Wikipedia's rules demand that no original research is included on its pages and conclusions are not drawn.
Past participants at these events have included activists, journalists, Quaker members, and even Cameron's own mother, building on school lessons where students were taught not to trust the platform because anyone could write it.
Organised to put more detail about the arms industry into the public domain, the gathering is part of an effort by new recruits to tackle a neglected topic on the collaborative online encyclopedia.
Although editing Wikipedia requires just a few clicks to publish a change, ethical complications quickly bubble up as the blurry line between activism and accurate dissemination of information stress-tests the platform's rules.
For arms industry page editors, those feelings can disappear over a few hours as they experience the reality that when you write something on Wikipedia, it appears immediately on the internet.
