For the same email, I changed the lang setting in Adwords, and the adsense is also changed to the same lang setting. Is that a cookie issue? No, because the lang setting in Adwords for email A does not affect the lang in Adsense for email B, so the server keeps tracks that. That is a No No. For everyone, you should never use the same email for both acconts, because, Adsense will know exact your credit card number, and Adwords will know how much you make from adsense (hidden coversion tool only known to google). There are also tax issues. And Adwords will get your credit card number and Adsense has your SSN. Wow. They can call your credit card to transfer funds now. Later when they have direct deposit, they can also do Direct Withdraw. Is is called ACH pull and ACH push.
Are you naked yet? FBI hears what you say, Microsfot knows where your PC is at. Google has access to your credit card. EV1 has 100% of your source codes. Kazar knows how much porn you downloaded.
Next time, google will have this "To remind your password in case you forget. Please answer this question as the secret key to recover your password. What is your mother's maiden name?"
Adsense and Adwords
Umm, they're the same company. Of course they're linked.
They can call your credit card to transfer funds now.
I don't think Google needs to steal money from you. Besides, they don't need your SSN to transfer funds from your credit card -- they have your credit card number because ... that's how you pay them.
What is your mother's maiden name?
Just make up a name.
