This is mostly a problem in the banking system, and it is wrong to feed it back to the credit center. But it's also good for you. The line of 0 means that you have no debt in this bank, and inquiring in other financial institutions will reduce your debt. Of course, there are disadvantages. If the bank is relatively large, other financial institutions will refer to its credit status and may reduce the credit line for you.
So it depends on how you look at it.
