clicking on your own ads using VPN, your adsense account will get banned once it would be found by google. They didn't take much time to findout it. Try to avoid these methods and concentrate on genuine traffic getting steps.
You do not want to risk it, most VPN service IP's end up getting flagged for this sort of thing eventually. You may get away with it for awhile or you may get hit with the ban stick your first time. take time to create something of value and you will do just fine without cheap tricks. Trust me at the end of the doing things the right way is less effort to have a sustained income than doing something shady that you have to rebuild every few months.
If the Adsense click is originated from the same IP Address as the one used for accessing your Adsense account, your account is flagged. Cookies: Most home users do not use static IP Address for Internet connection. In most cases just disconnect and reconnect will give you a new IP Address. But don’t forget, Google has set cookies on your computer. Hardware address: MAC address of the LAN card, modem, and router works almost like a fingerprint. I’m not sure if Google can track this, but probably they do. They have rocket scientist, remember?
also Search Engine Ranking – Google also detects your website or blog search engine ranking do detect consistently traffic.
I agree. Why take a change? I know this forum doesn't (usually) cater to anyone who might want to use unethical means of getting ahead.
