I tried making my first post a bit ago, and was told that there had already been a post from my IP within the last 360 seconds. As I have no router, clearly there is another person secretly hiding in my house using my internet, with a hidden computer. I am going to have to assume that he lives under the floorboards, and has tapped into my electricity and cable line. The only reasonable solution at this point is to begin ripping the floor apart, looking for the intruder.
Or, it may just be that the forum software is mistaken.
Some ISP assign the same IP to many customers, maybe that why you had the 360 seconds warning - or you logged less than 6 mins before posting
