yes i have been baanned to all adsenses and did not used the same adress.I have 6 adsense accs and manage them on 1 device (one WLAN) for 2 years. i never had the problem: "...has been banned because i have conected 3 adsenses on a ip".
- do you get banned with all of your 3 adsense accs?
- have you use the same post adress for all accs?
