Nice work @crokkon :) As a follow up analysis I would be curious to see (and I think it would add a lot of context to this) the earnings from this farm over time as well as the number of accounts. How much Steem/SBD was withdrawn from network? And if you do look at that, it would also be interesting to see if there was a noticeable reduction in income potential after HF20 and the dust vote shift.
If you look at the post by @supposer here: https://steemit.com/utopian-io/@supposer/how-steemit-is-infiltrated-by-abusive-account-networks
Some networks do get big enough that they become dolphins and use their ill-gotten SP to spam farm. By that point, it's near impossible to stop them.
Thanks, Carl! These are some interesting ideas for a follow-up :) The number of accounts and the growth over time is shown in a graph above. This network had author rewards of around 8 SBD + 10 SP in its last week before undelegation, plus a bit from involved accounts that have a few hundred own SP. The 160 SP after undelegation give a rough picture of the "lifetime earnings". Good point about the dust vote shift - living off hundreds of 15 SP accounts which suddenly have a vote "worth" only 13.8 SP per vote certainly makes a difference. However, the rewards in general changed quite considerably over the HF, so the plain numbers would probably give a biased picture there.
