The IP address could give you away if you have a static IP address. However, you could be legitimately sharing an IP with another person, like if you post from the same school or something like that.
Dude I was about to click on #eoff and ask you. xD
That's true, I mean me and my bf share the same network so we would essentially have the same IP, so by that note, it'd look like he was a second account, when in all reality he's just on another computer!
