possibility of deleting all pending listings?

hello, my site was spam attacked recently and i’ve ended up with over 9000 spam listings that are all set as pending. i can go to the “pending” folder and delete 20 at a time but this is still going to take ages – is there a way to delete the whole lot in one go?

i don’t want to delete the “good” listings, just these rogue “pending” ones.

thanks loads in advance
jim
