How do Goldsites protect from chargebacks?

Just noticed big name gold sites are accepting credit cards thru g2a without id required, how are these sites protecting themselves from chargebacks?

 

you shall contact banker for consultation: how does bank identify a charge back is reasonable or fraud. so you would ask from the buyer for required files in case charge back happens, and you can offer to bank for evidence proving a fraud charge back.

 

you both are retards did you even read post. nvm

 

G2A have a good chargeback system.
