Buying Credit And Tradelines? Is This Legal?

I have loan clients recently asking me about the Ads they are seeing about people selling credit and tradelines.



Basically it seems to work like this:



You pay $400-$700 per tradeline.

This person has seasoned (24+ months of credit card history per card) and they add the cleint as a extra card user on the account.



The client now has the new seasoned tradeline and credit history added on credit report and the benefits of the history....



Supposedly this will instantly enhance the score and make a tradeline to use for lenders.



Sounds like fraud. What does everyone think?



I advised my clients to stay away.



I know how to rapid rescore and simulate crdit repair through my firm, but I never have heard of this method nor the legalities of this.
