Never saw this happening before. Do you have a static IP address along with a same password for all of your accounts?
is it even allowed to have multi accounts? My one and only guess would be that he was playing on wifi and someone else was playing also on the same ip
It is allowed to have as many accounts as you want until you start using them for faucet farming or spreading fud in the chat. It is possible that the site might have merged the bets made with same IP address.
