I don't use AMR, nor have I seen how it's programmed. But problem seems largely in error handling from my view.
It seems to try endlessly in getting what it wants if it encounters a page it fails to parse, rather than giving up. I doubt the users are enjoying the endless active internet usage either, repeatedly downloading a broken page.
From what I can guess, all you need to do is remove the auto-check for new chapters on AMR.
Also, as I said previously, the ban isn't permanent. It keeps on cycling. If you stopped using it, you're likely off the ban list already. (recheck happened few min ago)
And it will reapply, once again, if you haven't disabled it.
