Very sorry about that - we intentionally don't show a warning like that, as it would be a tip-off to the real spammers, unfortunately. :-( If you're ever not sure, just log out and view the thread - if your replies aren't displayed, then they've been marked as spam.
Since it looks like your replies are continuing to be spammed, I suggest you contact our Akismet anti-spam service directly, filling out the form that will appear when you type "spam" in the text field, and choosing "I think Akismet is catching my comments by mistake" from the selections:

I will move your followers now - please stay tuned.
