This appears to be P:SYN. It is basically the work of one user, who has written several closely-related articles. The principal source cited in these articles is Elart von Collani, who runs a company called Stochastikon. The company name matches the username of the article author. Who has never, as far as I can see, edited any article without including a reference to Elart von Collani. Guy (Help!) 00:48, 18 November 2017 (UTC)
