your customers are getting AAAA addresses when looking up google addresses...so their
clients are trying to use IPv6 to talk to google..... so doing anything to that traffic - blackholing
or just denying it, WILL affect the clients. 

give clients their own bigger blocks - or identify the clients violating policy (what the policy
they are violating?) - you'll probably find the ones getting the captchas are the ones violating! ;-)
