It's in the original thread. He said..

I have been trying to hack hotmail accounts and can not do it. There server keeps banning my ip once i try 50 or 60 p'wds. How do i stop the server frum banning me?
I added the bold. Whether he was trying his own accounts or whether they were someone else's the intent is the same. He is attempting to break into a portion of Hotmail's service without their expressed permission. The act he is trying to do is to break into a computer system. In law, the attempt of something can be reason enough. One of the best examples of this was from a few years ago (around the mid 90s). A gentleman had been working for Intel and decided to try a little trick on their network, which he had access. He found a flaw and told them. He got arrested and found guilty (does anyone remember who this was?? Old age is interfering). The reason was that he didn't have expressed permission to do what he did, even though he had an account on the network.

So unless Hotmail has given infinite loop expressed written permission, he is doing something he shouldn't.

Besides, it's kinda lame to hack hotmail. I mean geez. Who wants all the pr0n and "enlarge yer penis for $4" ads?
