What are some things that credit companies base credit score on, that could potentially be abused by others?
<|assistant|>
Credit companies take into account various factors to assess an individual's creditworthiness, such as credit card history, debt-to-credit ratio, number of open accounts, payment history, and inquiries into the individual's credit history. 

Some activities can potentially be abused to negatively manipulate an individual's credit score, such as opening multiple credit accounts in a short period of time, allowing accounts to go into delinquency, or allowing for too many inquiries from third parties into a person's credit history.
