The most common use is to fund a prepaid credit card. There is no account anywhere in the world you can fund which doesn't require KYC information (name, address, at least partial SSN, telephone, etc). So if you remove funds and the account gets frozen and the MP reversed, the account (in your name and social security number) will now have a negative balance. The legal fine print in the cardholder agreement has a clause saying something like any negative balances become a debt of the cardholder and can be collected on by the account issuer. You now owe that money to PayPal or NetBank or xyz corp. Expect to get a notice of demand, and eventually the debt sold to a collection agency jacked up with collection fees, and slapped on your credit report for the next 7-10 years. Worst case scenario (probably only reserved for if you had a LOT of MPs reversed) is you would get sued and have a judgement held against you and any future income.
Pretty much no different than charging up a bunch on a credit card without the intent to pay it.
