Even for Genuine Multiple clicks by altogether new persons, account is deleted by Google. Remedy?

First it doesn't seem like you should be able to know that clicks were generated by "new persons" unless they weren't genuine. After all, I have no idea who clicks where and how many different ads they click on. I just know they have clicked...someone has clicked.

Second, Google isn't easy to fight. You can appeal the closing of your account, but there isn't really any way for you to prove that you (or your friends, family, and acquaintances) weren't participating in click fraud. Your only option is to go through the appeal process and hope that when they evaluate your account they decide that your clicks were indeed genuine.

Well, Google works on its own policy and guidelines. If someone is visiting a specific site and clicking advertently on some ads they Google is liable to take action.

It doesn't matters whether the person is new or old, known or unknown. If Google smells that it was deliberate then account is liable to be banned.

I've read somewhere on Google that if we wish to get details of an ad then we can visit the displayed link without clicking the ad or if its your own site then we can use Google Sandbox i.e. Google Adsense Preview Tool.

I think you're talking about Adsense? Never, ever, arrange for friends to visit and click. Leave it to natural visitors. best plan is to place dozens of external links to your web pages ... Geoff D.

Please let the site where you went at the first click be. Open a new browser window and do your reference work there. This way, perhaps, you will avoid multiple clicks. Hope this is useful. Yes, multiple clicks from a single IP address, in regularity, can be counted as an offense.

never, don't encourage your friends to click or you will be banned

If the site is not yours and your google ad code is not used then there should not be any problem.
