There is a porn site accessing my home page over 1,200 times a day under at least 30 constantly changing aliases. My site previously had a referrer page which I believe made it a prime porn target. I've emailed the owner of the site and told him to stop, which he simply ignored. The porn site is based in Australia and I'm in the US, so I'm not sure if there is any legal, and cost effective, action I can take.
Anyone have any ideas?
