What particular, specific problem your method (by creating pob.voter) solves, which can not be done or solved by the original proofofbrainio account? Maybe I'm to dumb to get it, so please pinpoint it to me.

Voting automation (without true, read-it-first curation) is easy and requires no human resource, it can be done in no time, if the owner has a wish to.

Where the actual problem originates is that true good curation needs to do "read-it-first", and this requires very limited and high value resource - TIME. Which none of us have in excess.
