> Do you know how you correct mistakes in your Equifax-TransUnion-Experian composite credit score? You mostly don't, and you most likely can't take them to court, because they think you are bound to arbitration.

Sorry, that's not true at all. I went to Experian late last week to set up a fraud alert because of the Equifax breach, they showed me my credit report and had a button to mark things that were factually incorrect. I did so and submitted it. They did some sort of investigation and removed the data because they couldn't verify that it was correct. It was as easy as filling out an online form. (Actually, I think I had to call about 1 particular item, but it was handled over the phone.)
