I think this exchange adds coins without the consent of the coin developer. Of course it can be good since it increase liquidity and may be bad since its may increase dumping. (ex: graft I think)
Why should the coin developer have to consent to their coin being added to an exchange?

Cryptocurrency is meant to be permissionless and decentralised. It would be ridiculous if you needed to ask the developers for permission before you did anything on the network.
how much do they pay you ?
They don't pay me anything, the only time I've contacted TradeOgre is to get support when one of my deposits got stuck. I just think that you are being very unfair to this exchange.
We need to do our best to support smaller exchanges, pools, etc. so that they continue to exist and provide an alternative to the big exchanges and their KYC/AML rules.
