I don't know why people continue to post this false information. It usually comes from those whom have never tried churning cards and are just repeating erroneous statements that they're heard others make.

Can churning hurt your credit score? Yes.

Based solely on their post here can you say that the OP's credit score will be damaged due to churning? Nope.

There are other factors that go into one's score than how often you apply for and open new accounts. If your credit is already awful, then yes, churning will most likely further damage your already poor score.
