But that's missing the chain aspect. Should be "send 1k sats to the 5 people below, add your name to the top of the list, take the bottom name off, and forward to 5 people" or something like that, no?

The starter of the chain is always the most profitable. The killer of the chain is the risk. The spamming of the audience is the work. The profit potential is 3.9M sats at 1k sats per chain name for each chain that goes 5 deep without interruption. But I don't think anyone is dumb enough to do it.
