Hi XFactor,
There are three possible theories on someone who have not earned any merit more than 9 months till the launch day of merit system:
- They are spammers. During the 9-month period, they kept posting/ spamming; and have not contributed anything deserves merits.
- They have been totally inactive during the 9-month period.
- They are service providers, such as mining pools, Escrow services, bounty managers, etc. Those sort of users mostly hard to get merits.

So, the figures above are only for reference. We need to have a forensic analysis with a bit deeper analysis to be able to really discover the facts.
