This is happening to me too. I've had several posters names show up, the latest being cympreni and nynaeve. Now it says wild~hair again. It seems like posting doesn't work and I get a security error when someone else's name is showing up. When it's my own name, all works fine.
I am on the website as well.
ETA: One of the names that comes up for me is junipero and I saw someone reported them as a spammer. FWIW.
