Has anyone here ever been banned for a post that's been archived? I'm seriously doubting that reporting an archived post even does anything.
No. IIRC the IPs are stripped when threads get archived. Although this may have changed.
I've seen threads get deleted from the archive after I reported them but this hasn't happened in a long time.

Also if you report a thread when it's alive you have to report it again after it gets archived.
