Well I broke it somehow.

I imported the .xml file, set the critera in the AdminCP, and then edited the invalidid phrase and it worked fine at first.
Then I went and created a new discussion thread (similar to yours) that the
invalidid phrase error could point them towards. Lastly, I went back and re-edited the invalidid phrase with the address of that newly created thread.
Once I did that, I no longer get an error notice anymore when I post spam now.:disappointed: The MOD still works, in that it seems to perfectly catch what needs to be held for moderation...it's just it doesn't tell the author anything about what's being done.(i.e. Doesn't seem like the invalidid error msg is being called upon any longer)
After posting, the screen refreshes and you're brought back to the thread, but w/o the spam message showing up you just posted.(as it's being held for moderation now)
I went back and reset the invalidid phrase to original and it didn't help any. I went back and re-imported the .xml file and it didn't help. Any ideas as to what else could be wrong??
EDIT: Nothing is broke, I just didn't understand how the MOD works. Turns out it still works perfectly for NEW THREADS. It just doesn't show the person posting a REPLY or QUICK REPLY the error message as I thought it would. In either case, it still marks the message awaiting moderation as it should though. :up:
