Create a game to identify people in the category https://commons.wikimedia.org/wiki/Category:Unidentified_figure_skaters using suggestions based on the participant list of the event (all pictures are categorized in an event)
It could look something like the Visual Tool of mix n' match, with the unidentified picture on the left side, and suggested matches on the right (https://tools.wmflabs.org/mix-n-match/visual_match.html#catalog=545) with a filtering system by gender/discipline in the middle based on the SPARQL query
