Ask your friend about that, please. The US happens to have jurisication in this area.
How did a US company manage to close down 555 websites based in Pakistan.
Google is subject to US law - do you know what a google ban means? It is a death sentence, in case you do not know. So, if someone decides to take you on, seek an injunctive relief against the sites you are shilling for here, your physical location in Pakistan does not matter much. If a court order is issued, search engines have to comply and the sites die. It is that simple.
Same can happen to you also.....
