the blockchain is public...all your transactions, all your cards, all your coins...your wallet contents, your game assets...all these exist on a public ledger...
and wrong? 'very wrong'? as in morally wrong? ethically wrong? or just you don't like it 'wrong'? Exploits might be...but botting is allowed within the ToS...so if it's allowed, and not illegal, then how is it 'very wrong'?
