I have a Live Support app installed on my website and I see a visitor every day, all day long for the last 3 months. This visitor has 3 or more IP addresses, but doesn't change them too often. It seems his (or her) browser supports Flash, and definietly supports JavaScript, because that's required for the Live Support app to collect data. Any idea what it might be, why would someone do such thing?
I tried to invite the visitor for chat, but my request was ignored. I also blocked two of his addresses, but he reappeared with a third one. He never visits any other page, just the one he landed on, usually our homepage.
