I was curious about that scenario too. That would mean that (eventually) only miners profit from funds sent to addresses with leaked private keys.
After a while it makes you wonder if it could actually work the other way. More and more people stop running the bots since it really does become pointless and they are slowly forgotten about.
Kind of like the way junk fax senders have been disappearing. Just no work / no profit and more and more people pursuing legal action against them. They just left the field.
Yes in theory this is 'free money' just by running a script. But the 1st time they go to consolidate all the dust they have since fees ate the rest do they just walk away.
