Expired Article on Domain TLD Blogger

I have a serious problem ...
as you know that it's "expired article " may be freely used by others to republish the article in question and this because:
The domain that they have already expired and hosting already can not be used again because no extended period of the contract.

Okay. just to the core of the problem. ..
I have a blog with the TLD .com and use hosting blogger dot com which gives free unlimited ...
Suppose domain TLD I have already expired. What will happen to the Status of my article which was already indexed?
What is the status of my article so it expired?
Please answer and help me. ..
Don't be a silent reader Please..

Sorry but its a bit confusing to read your problem here lol.

I have no experience of blogger platform, but got a similar situation, that is, using the Google Site platform. A domain attached a google site url and then one day, domain got expired. But still, the contents are all indexed, so I think these contents, you can not use again.
