Yes, there is an old saying, when you find yourself in a hole stop digging.
I would say that it could be cleared but you might need some acid or maybe
take the toilet ot and mechanically clear it. It kinds of makes one wonder
about the installation if it gets so easily blocked in the first place
though.
I wonder if it was in reply to a very old post, but as the joke goes, we
now have nothing to go on!

Hello all. Please can someone help. My brand new toilet somehow got
blocked. So, I poured a cap full of caustic soda down it and some boiling
water. Nothing happened. So I kept doing it, so much so that the crystals
have totally hardened and now, the hole has almost totally blocked up and
none of the waste is being flushed away. How can I dissolve the totally
rock hard caustic soda. Can I salvage my toilet?? Can it be cleared away.
(Almost 10 days now). Thank you for your help.
