Clearing mass player subscriptions

Hey guys

ive managed to somehow subscribe to around 10k players who i have no interest in and every push of the 'continue' button is lagged every turn by tons of new reports from these players.

ive gone to .news / manage subscriptions' but cant seem to select all the players in one to to unsubscribe them - does anyone know of an easy way to do this other than going through each player and unticking 'contract'?

Ive tried selecting all players in 'player search' and subscribing them with the view to unsubscribing but it crashes my game ;(
