The screenshot shows the btc address where to put the coins.. Why do you say that a different address was generated?
The screenshots of your conservations do not help here... So can you tell why you call the player a scammer? How did he try to scam you?
did you see the bitcointalk profile satoshi. he said this is my bitcointalk profile. here the link.
https://bitcointalk.org/index.php?action=profile%3bu=31. check out his last active date is December 13, 2010. he claim this is his bitcointalk profile and offer me to calculate house edge for 0.1 btc. Now he is saying it was a joke using another bitcointalk profile.
2. he is using our website html code to change the bitcoin address where the coin is sent and claim that is made. We know this problem and people will use it for scam. that's why we save the player bitcoin address and our bitcoin address to confirm that the transaction is actual made on our address or not.
3. he is not he first one who using this method of scam and won't be the last one. we are facing people like that a lot.
