The important side note on this is:

This check is across all of your characters on your realm.
The 5 per 1 hour can be worked around with a different character.
Though the 30 per 24 hours is for your account per server, regardless of character.

More importantly if you are doing things like frequent instance resets to look for a rare mob (like Jed) utilizing multiple characters you'll accumulate those 30 IDs quite fast.
