Thank you and to the first answer you are right. I host my sites on a shared server. The company tells me that they are unable to help block what they call stalkers. Which they said and accused me of giving access to the site.
Second How does one make sure that this doesn't happen? I did go to your site and I do understand monitoring, but if you are not allowed to do this then what? Example lets say a sight is hosted on Hsphere and the company claims after you notice someone signed up with a suspicous address that made us look deeper. We traced it to Nigera which was in conflict with the American address giving. When we talked to the techs of this company they said they had noticed someone "stalking" the site.
When I questioned the tech they said they couldn't do anything including not even warn me cause it was not their job.
Still hope you will help me please.
