Ah, I saw this information in the forum.
Activity just increase, It can't decrease?
Yeah, activity points not only increased because your activity points will decrease by 14 points every 116 years.
Read here:

Perhaps this is a joke that went over my head but that's not what that post means - there is no decrease but each activity period is slightly longer than 14 days.
Besides there is a chance we might be using the new forum software in 116 years... not so sure about that one though.
