How can I be protected in the Internet ?

I need protection in the Internet, because there is someone who is insisting on bothering me and provoking me problems. I tried to do everything I could in order to get rid of him, but he doesn鈥檛 leave me alone and he keeps provoking many problems to my Internet business on purpose, because he wants me. I鈥檓 attractive and I鈥檓 used to face that kind of problem, but in the Internet I cannot be stronger than a veteran鈥?
I cannot prove anything against him because he has one of the biggest sites in the Internet for years, and he is American, while I am in the Internet only for two years and nobody would believe that such serious 鈥淢ister鈥?is torturing me so much鈥?I have no way to prove that he is provoking me all the unexpected problems I have in my business.
I鈥檝e being too tolerant with him, but he keeps annoying me all the time! How can I find an Internet guard, someone like a body-guard, that would protect me from his attacks and would scrutinize everything and verify why I have to face so many delays, betrayals from providers and many other unexpected problems?

Your business...do you own the domain? If ya do, you can block him from accessing without too much trouble depending on who is hosting it.

Might help to know more about what he is doing to you, where he is doing it and how he is pulling it off...

use linux instead of microsoft, its free
get ubuntu.
