an ip is basically a computer thumbprint. So "OPas" pretty much made every post from YOUR COMPUTER in YOUR HOUSE or where ever you post
dumbo
eh an ip is not the computer thumbprint. it is internet server thumbprint.
I use my laptop in tons of places, the mall, university, and i even use my cellphone wifi.
it could be that user perhaps uses same network? or also uses internet in public places. i dont know
but i know for a fact that has nothing to do with one computer but with internet provider IP address
