RE: Some ideas for future POB Delegations from @proofofbrainio
My point was more directed towards the accountability factor, the upvote isn't a huge deal in the grand scheme of things, just that it's a contributing factor to what makes the efforts of curating on the account worthwhile for the individual.
It seems like it may be better to set up an account to curation trail follow these three members and then they can receive the upvote from the account at the end of the week or whatever. This reduces the chance for abuse and curation trails can be easily disconnected if anything fishy goes on without the need to change the posting key or remove the delegation.
If it was a separate account that those three members had the keys for, they'd have to curate on their own account and then the curation account which would mean more work.
