It looks to me much like the way to sell marijuana by selling an old newspaper for $50 with a packet of weed as a free gift with it.
I suppose that $1865 is a reasonably small price to send $500k to someone concealed as a service charge.

So they may have just forgotten to add the field that sends the money in a self-loop, and by default the account was drained by the miner fee.
This is obviously a terrible design but it can't be changed.
you can do it other ways, but it'll cost more. bitcoin's fairly freeform like that.
