Joto , i write that here to suggest u to move those keys that existing on Chie Game Store bot account to any other place , cuz may be that bot got Trade Banned by Valve any time and the keys that planed to be refunded staying stuck with it forever .

Thanks

You are right, the bot is trade banned (along with other alts of Chie Game Store's owner). But anyway I think those keys could not really be saved anyway because whoever storing those keys will be considered one of the alts.
