I had no other problems with any other internet site that I tried. So, I got the bright idea to try to log on using a program that hides my IP address.
It worked, obviously. O_O
I tested it... I unhid my IP and tried accessing a post to comment. Nope... couldn't do it. I hid it again and had no trouble at all.
Obviously LJ doesn't like my IP address any more, but why? What would cause such a thing?
