On that Advertisers settings page, it is really lame you cannot click through the list of advertisers in one fell swoop, disabling ads from all of them at once.

On that Advertisers settings page, it is really lame you cannot click through the list of advertisers in one fell swoop, disabling ads from all of them at once. There is no "select all." No, you have to click the X in the corner of each one, then click View More after every 12 you have disabled. I got through about 140 before giving up. I think this was intentional.
