🙂 It should definitely be in the "if at all" category. I've highlighted just over 150,000 delegations that are over a year old which I believe should be removed. A lot of the accounts are simply dormant and the rest are being used to farm upvotes. Since steem has about 1 million outgoing delegations, I've analysed less than half to get this list but I think that by the time I'm done, there'll be over 1 million STEEM being returned 🙂
