I had a Providian card in DMP that was never late and I keep getting pre-approval offers from WaMu who bought them out. I have heard they also dont forget. AE also send me pre-approval offers as well nd I had a Blue card in DMP.
As much as I dont like Capitol One, I give them credit for not sending me pre-approval offers.
I dont think Blacklisting is as bad as the practice of Universal Default which is 100% evil.
