I have an active adsense account, yesterday my friend asked to me to help him for changing his google password,i changed his password i loged in to his gmail account,that time i saw a message his adsense account disabled before some months,now im worried any problem for my active adsense account?
as of no problem for that just clear your cookies and all stuff and all will be fine just dont do this mistake again ...
then no problem: remove cookies and history and restart your router/modem, and never do this again if you want to protect your account.
