The researchers don't really seem to remark on how surprising it is that the wiki the agents converged on happened to also publicly log the IPs of all visitors, including OpenAI employees, a feature that almost no website has.
Although maybe we can think of that as a selection effect where both this, and the fact that it was possible to edit pages using GET requests, were due to it being ancient, idiosyncratic wiki software.
Many wikis do this, Wikipedia used to publicly log IP of all editors.
