Avoid duplicated results

What is the best way to not show duplicated results? So if I track an user follow activity and someone follows, unfollow and then again follows and user the activity only shows up ones.

Could you clarify your question? You want duplicate results or you do not? I'm not sure I understand.

So I figured it out in the meantime. I had to destroy the activity when I delete an association (for example with an unfollow), I think this should also be covered in the tutorial.

IMO destroying the activity is counter to the idea of keeping all of the actions that occur. Your fix of removing the record 'works', but does create a data integrity issue. Not that you would be worried about that on a tutorial. But IMO I would probably write a helper method that filters out actions of the same type within a certain timeframe.
