What's to prevent buyers from simply creating a new email or from using a different ip address and continue in their same practices? On your beat site, could you post your contracts as downloads for buyers to know what they are agreeing to by buying the beat, and then adding a section in those contracts that if they receive a refund, all their rights to the beat are revoked?
what about also adding something in the contract about the PRODUCER not being responsible for BUYER's credit card being used by BUYER or any other party to make purchases from PRODUCER?
If enforceable in the court of law could you also put terms in your contracts, that read something like:
"should [BUYER] obtain their refund by disputing the charge on their credit card, without first contacting [PRODUCER] in written form, and the [PRODUCER] can prove that the product was for a fact delivered to BUYER, BUYER must pay fee of $XXXX. BUYER must pay the fee within 30 days the dispute claim was made. If fee is not paid within 30 days, the amount owed to PRODUCER increases by ten (10) percent daily, starting on the 31st day, until complete fee and late payments are satisfied.
Should BUYER breach any terms outlined in this agreement, PRODUCER reserves the right to pursue legal action at a time and place of PRODUCER's choice.
Could something like this work? Chances are beat jackers won't read these contracts anyway if they already know what they are going to do...I'd love to see their face when they receive a court summons.
