How activity is being calculated?

like how I'm getting items while being offline?

you're so good at the game you're rewarded for joining

When players get items in one of your worlds, there's a chance you will get an item too.
Right now there's a bug saying that you got the item for activity when it should say that someone played your world and got an item.
