I disputed 7 old accounts with Transunion and they were deleted.

I am thrilled.  They were old anyway, but I am still glad they are gone.  I disputed these online yesterday morning and received my dispute status and it says they were all deleted.

Congrats! Did your score change any?

And how old were they?

I did that, and my fico score dropped 50 points.  If the old accounts were accounts in good standing, you may have just removed the longevity portion of the fico score.
