As a lister:
- I get request to list a faucet.
- I claim once.
- I list the faucet.
- Few days later the faucet suddenly stops paying ref.
- The faucet continues to pay normally.
---------------------------------------
At that point I delist the faucet and the faucet owner returns to me saying that he did not ban me and he don't understand what is going on.

It has happened too many times to be a coincidence or a dishonest faucet owner. So it is either a bug or a "feature".
