And stolen credit cards get reported and the keys get banned, not defending G2A but it happens, G2A don't sell every key, People can sell keys they have on G2A, So if i went to buy 4 physical copies of a game i can take the CD keys and sell them on G2A for a higher price. I know people who have found a retail store selling games for a lot cheaper than normal retail price for them to go and sell them on G2A because they can make a profit, Because its an open Market place though nothing stops someone from stealing a credit card and selling them there, but when the credit card is reported as stolen because most PC games are digital, they are easily traced because it has a digital trail.

Going by these standards though even ebay or amazon are scummy because you get the odd bad apple.

Only time it doesn't work that was is if the stolen credit card goes and buy a ton of physical copies and sells them, retailers don't take copies of CD keys so much harder to track which CD keys have been stolen.

Should people who buy Steam games when their on sale for cheap then go as sell them online not be allowed to do that? is doing that any different from trading in games on consoles? nope in fact the developers still made a sale because someone actually bought the game from steam.

Like i say not defending G2A but, seems to be a lot people really don't understand it either.
