Apparently I can't post to 2ch any longer. Great.
As far as I can tell, the error message I'm getting says "Foreign domain restricted (.se) ... Use a 2ch viewer." -- would that mean that the whole .se top level domain is blocked? Or should I read this as "Your domain, which is in .se, is blocked."?
Annoying, either way. I guess I'll have to try and find a proxy now.
