Be forewarned...the dreaded adsense emails must be going out. A family member of mine received the email today citing they would be paid up until next week but Google didn't like their "business model". She's had the account for many years without any problems at all. She was using adwords for some of her pages but otherwise they wasn't anything shady going on that we can determine. The landing pages for adwords were filled with the exact information cited in the ad. After reading the other post going on about this I've shut down all of my adwords accounts since that seems to be the one constant. I am concerned about one thing. The email says all related accounts will be shut down also. What exactly is a related account? We don't live at the same address but once a month or every two months I've logged into her account to check on things while she's out of town. Will my accounts be linked to hers and shut down also?
One of the first things I learned about Adsense is: You never talk about Adsense. Not to your friends, not to your co-workers and not to your 'family members'. They can cause your account to be shut down, and you can cause their account to be shut down. But to end this rant and answer your question: Yes. It is possible that Google wil shut down 'related' accounts. For example accounts that have been operated from the same IP Address. But since Google moves in mysterious ways, only time can tell. Best of luck!
