You're leet!
I think this might be because when the page loads, OmnomIRC checks your current post count. Since a SMF easter egg causes a post count of 1337 to display as leet instead of a number, it probably thinks it's 0 or something. Just post again outside Randomness and you should be fine.
(At 100000 posts it says "geek")
Also, I guess that bug can discourage people from stopping posting completely when reaching this post count. I remember on UTI Speler stopped posting for months after he reached 1000. X.x
