> Do you know whether Facebook still stores that data?

Honestly I couldn’t answer that. I never really touched production userdata (mainly because it was scary and also it was in PHP or some horrid transpiled interface to PHP)

My gut feeling is that facebook doesn't throw data away unless its forced to. So its probably there on your graph somewhere.
