I totally agree, but they will never do that because ASX earns $ based on volume. So they allow all kind of BOT trades. But from retailer point of view BOT trades do not matter much, unless you are day trader. For example today AGO went hard up 9% on a genuine high volume. So BOT trades would just be swamped in those trades.
I avoid low volume and low liquidity stocks. This way I do not care about BOT activity.
