Pre-approve or block all ads for selected AdWords accounts

To pre-approve or block all ads for a particular AdWords account, locate an ad related to that account in the Ad review center. Hover over the ad, click the gear icon and choose either Pre-approve this AdWords account or Block this AdWords account, depending on your preference.

You can view your lists of pre-approved and blocked AdWords accounts later by visiting the Settings subtab in the Ad review center. On the Settings subtab, pre-approved and blocked AdWords accounts are listed by account name, i.e., the network or company name of the Adwords account. If you see the account name "Anonymous advertiser" it means that the AdWords advertiser has not specified a network or company name.

Note that when you block AdWords accounts whose ads you've previously approved, it may take up to a day for them to stop appearing on your website. You'll also notice this delay when you approve AdWords accounts that you've blocked in the past.
