Sometimes this happens automatically (By accident -- akin to throwing out the baby with the bathwater) -- there's several different pieces of automatic IP blocking software since Blur Busters is under attack from time to time (hackers). It's possible that somebody else at your ISP got automatically blocked by this software. Send me a PM and I'll work to manually unblock your IP from the system. The strange formatting problem is being fixed this weekend -- keep tuned.
Thanks for being patient!
[EDIT: This is now fully fixed!]
