The article has the hallmarks of undisclosed paid editing. Hours after their first edit (unrelated), a  creates with their second edit this well-formed article with 46 impecably formated references, an infobox, correctly piped links, categories, close compliance with the Manual of Style, etc. Their only other edits, the following week, are to create a disambigution page for the topic. Later on, {{U|Greenroomcreative}}, another SPA, adds a studio portrait. Green Room Creative is a New York City marketing agency that boasts Carlson's company Rowing Blazers as a client.http://greenroomcreative.co/ A third SPA comes along and, after a few hours updating this article, submits a draft about the company, Draft:Rowing Blazers. A fourth editor, not quite a SPA, spends 7 of their 16 edits, spread out over five different days spanning nearly a month, to tweak Jack Carlson (rower) and Draft:Rowing Blazers, and link to Carlson from other articles
