When did reblogs start getting tracked?

[Nate Westheimer]

Anyone at Tumblr know what date reblogs started getting tracked? I want to show users only content they created, so I'm getting reblog_info=true and excluding content that has reblogged_from_id. But in just testing my account I'm noticing that a ton of older posts (I've been a user for a long, long time) dont have that data even when they were reblogged.

Would be great to give a date to my users that if they've been on Tumblr longer than n years they can expect a different experience.

Thanks!

Hey Nate,

I'm not seeing anything that's in our code that would give a hard cutoff on any date, but I'm more interested to see that if you could post me back some of the post urls and post ids. I'm wondering if some of these posts you are seeing are in fact, just deleted parent posts. 

I've got a few other code paths to check out before I give you a 100% "no hard cutoff", but I figure I can do some checking in parallel on those posts :)

Thanks!
