Creating new accounts is the easy part
Keeping it is the hard one...
Here is the reason why no one will give you right infos. First, its a public forum, google is here too, so, if someone have a black working method, he would be sharing with you AND GOOGLE... Would you do the same?
Second, If you are asking such a simple question, then, you won't be able to get passed the obstacles coming ahead. It's like someone wants to be olympic winner and asking how to swim. The pro will tell him, it's not gonna work, you need to take it step by step.
Now, for your answer, you are trying to cloak google adwords which is the smartest company in the world.. Why don't you learn cloaking in a smaller company and then go advance as you learn more and more?
Once I tell you how to create new account and not get banned, what will you use a payment method? How many credit cards do you have? Does they have the same holder name? Then, you will get banned, AGAIN
Finally, here is a hint for your specific question, there are gazillion of traces in each single pc big companies use. And with google having access to your gmail, android mobile and everywhere else, you Can't hide from it using the SAME PC...
This is should be enough to push you in the right direction
