Your website has just been visited by an installation of the OS2datascanner system running a scan.
The OS2datascanner system is a search engine, intended for internal use in an organisation, that applies search rules across many data sources. When it functions as a web crawler, it assumes that it has permission to scan target websites in their entirety, and so does not obey the restrictions specified in the robots.txt file.
OS2datascanner is developed and maintained by Magenta ApS for the OS2 consortium, but the installation that has visited your website is not necessarily under the control of these organisations.
