If the club doesn't want to take a financial hit on this, they should use a few games in the early gameweeks against some less recognised opposition, like Bournemouth, Crystal Palace etc., so they probably pay less to buyout the ticket at the touting website and still have like 15 home games ahead, they can cancel the ST and put that seat back on regular sale on club's website for the remainder of the season, which returns the invested amount + returns the seat to the fans who actually want to go to the game.
Those on ST waiting list might get to their 'promised land' the following season or the seat might return to the bulk salem either option is better than leaving this seat sold at extortionate prices by the touts.
