Ok, so I had a mishap with the server, ended up reformatting the whole thing and losing everything. So now instead of Linux I am running a windows server from scratch.
I *think* the ban issue worked itself out now, we will see come tomorrow.
I had that user change his name, so he took out all the /\\/ stuff, and made regular letters, and it worked, so I think the problem was either those slashes or the O with the line through it causing the problems. I'd assume it was the slashes though, since those are often used in commenting etc.
