Not sure this is avoidable until regulation kicks in (similar to trading standards with current trading systems) or how much impact it actually has on the markets.

imho, he has inside info on users accounts and how they could impact price movement, but its not all that huge a benefit as you might think and wouldnt be that easy to exploit.
we can all see the order book of the exchanges, knowing which accounts have lots of 'potential' with high balances to move the market doesnt mean they actually will use that potential in a predictable way and cause obvious price moves to exploit. not sure what other info this guy could have that cant be inferred from the public orderbook..
 
unless this guy was actually buying and selling in large amounts to directly affect the markets (like bots), not so sure the shock value is very high on this story (in terms of impact on the average user).  

probably damages the reputation of the exchange more than anything... im sure hes getting more money from the fees than any insider trading info.

could be wrong ofc! i dont use their platform so not sure how reliable it is.
