Yeah we don't want all the freeriders just tag spamming POB, but if they do just to sell to hive, that's o.k. too cause it mans the POB will shift into the diamond POB hands instead. I say play it by ear, we don't have to do anything too harsh about that yet. Maybe those people who tag abuse won't make enough POB and get board and use other tags. Curation is key, as long as these spammy posts that do find a way in don't get excessively rewarded POB should be fine.
The reason it's different here is because of the Bitcoinesq low supply rules! People act different because POB is different.
