True thing: until recently you could remove hard inquiries from your credit report merely by pulling your own credit so often in one month using an array of daily monitoring services that you would overflow the field and bump off legit inquiries.
I did this in 2009-10, it had been going on for a while, and lasted for a while but sadly I hear they've solved it seemingly by nightly batch job to remove your own credit pulls.
These companies are just barely functional for their purpose.
Experian seemed to have their act together a bit more.
