The International e-Sports Federation has seen an outpouring of backlash this morning over a bizarre policy that prohibits female competitors from entering its Hearthstone tournament. A Reddit post first drew attention to the restriction by noting that one of the tournaments qualifiers, hosted by Assembly in Finland, stated that it only allowed male players. Assembly has tried to push the blame back onto the IeSF, writing that, since the IeSF World Championship Hearthstone tournament in Baku is male only, we can only accept male participants in the Finnish qualifier. IeSF did not respond to a request for comment on why its chosen to prohibit female players from the tournament.
