Activity score reduced from 3000 to 470

Hi
My Activity score reduced from 3000 to 470 .
Please let me know the reason.

Thanks
Ratna

Activity Score is only for the last month. Most of your LingQing must have been done more than a month ago. If you don’t keep up, it goes down to reflect the last month of activity.

The Activity Score measures your activity on the site in the last 30 days.
