The deletes work sometimes even if the account is a legitimate debt or could be marked "Included in bankruptcy" with a $0 balance.
It's worth disputing all of the accounts for any reason you can think of and see what falls off, in my opinion.
Just telling them that I was not responsible for the car loan because "It was in the bankruptcy, but my ex (name) is now totally responsible for this." caused a $20,000 car loan that previously said "Closed bankrupty, $0" to fall off, raising my score 9 points.
You can do this even if you're not in bankruptcy. Dispute things and 60-70% of the time they just fall off because the creditor is disorganized or doesn't bother to reply. It's sort of like going to court and the other guy doesn't show up.
One of the reasons I had a lot of good cards (for many years) before a really bad year hit me last year, is because I always disputed medical bills and stuff, so if anyone looked at my credit, it was fairly clean even if all kinds of stuff really might have otherwise been there.
This one time, a hospital debt collector couldn't substantiate a $15,600 bill and it fell off.
A lot of the reason your credit can get completely trashed is because a lot of people stand there and don't bother to do anything about it, or don't know that you can. I think that this has encouraged a sort of laziness in the debt industry where they really can't back a lot of that up.
