I think it has to do with their system's algo. They should amend how they calculate hubscores or add a new calculation algorithm specifically for new accounts and provide them a head start to solve this problem. However, such feature can be abused. There are hundreds of new accounts created every day that are basically intended for spamming. Providing them with a high hubscore might cause a negative effect on Hubpage's integrity in the eyes of search engines. So IMO, the system needs no revision. If you want a higher score, work for it. That's fair right? Anyways, welcome to Hubpages and good luck!
