I've commented a thread couple day ago on this forum, it means I have an activity gained. Then I realized that I lost my activity because that thread have been deleted by moderator or poster for a reason I guess.
If any post deleted for any types of violation then you will loss your post count. And your activity rank and post count same than you will loss activity rank too. But if your post count is more than activity rank then you will not loss your activity rank.
Related to "Deleted Posts" issue, what if I get merit on that thread, would my merit get lost too if that thread was deleted by moderator or poster?
You will loss only post count and activity rank but you will never loss your merit for being deleted a post.
Understood, thanks.
