I always wondered if Google would pay out a balance from an account that has been terminated but has accrued a balance of more than a $100.
I looked up Google's AdSense TOS just now and found a really long couple of sentences which explains it.
In the event the Agreement is terminated, Google shall pay Your earned balance to You within approximately ninety (90) days after the end of the calendar month in which the Agreement is terminated by You (following Google's receipt of Your written request, including by email, to terminate the Agreement) or by Google.
BUT!
Notwithstanding the foregoing, Google shall not be liable for any payment based on: (a) any amounts which result from invalid queries, invalid Referral Events, or invalid clicks or impressions on Ads generated by any person, bot, automated program or similar device, as reasonably determined by Google, including without limitation through any clicks or impressions (i) originating from Your IP addresses or computers under Your control, (ii) solicited by payment of money, false representation, or request for end users to click on Ads, or (iii) solicited by payment of money, false representation, or any illegal or otherwise invalid request for end users to complete Referral Events; (b) Ads or Referral Buttons delivered to end users whose browsers have JavaScript disabled; (c) Ads benefiting charitable organizations and other placeholder or transparent Ads that Google may deliver; (d) Google advertisements for its own products and/or services (excluding payments based on completed Referral Events); or (e) clicks co-mingled with a significant number of invalid clicks described in (a) above, or as a result of any breach of this Agreement by You for any applicable pay period. Google reserves the right to withhold payment or charge back Your account due to any of the foregoing or any breach of this Agreement by You, pending Google's reasonable investigation of any of the foregoing or any breach of this Agreement by You, or in the event that an advertiser whose Ads are displayed in connection with Your Site(s) defaults on payment for such Ads to Google.
And even more so!
In addition, if You are past due on any payment to Google in connection with any Google program (including without limitation the Google AdWords program), Google reserves the right to withhold payment until all outstanding payments have been made or to offset amounts owed to You in connection with the Program by amounts owed by You to Google.
So in short, you may or may not get paid for your balance. If Google sees that those clicks are all invalid clicks, then Google most likely won't pay you. Why does Google terminate accounts? Mostly because of invalid clicks. So, one can logically assume that most accounts that are terminated do not get paid out their current balance.
