this is my evaluation:
Good Points:
1. Attractive design.
2. No Ads.
Bad points:
1. need to update /refresh the page after each search.
2. A unique algorithm for some accounts is not working "Satoshi, Administrator, Staff, DT members,.....etc".
3. Closed source "Can you share your source?", I think the value of the accounts rose after the merit system.
4. Modify the value of the account based on merit points.
