Not only is this a way for you to keep your stuff, inform you what reddit knew about you and in general good to do with services you use every now and then - it also tends to be quite expensive operation for tech companies that aren't quite operationally mature yet.
In other words, strongly recommend making a request if you still have an account.
I made a request last weekend and never got an answer. Checking back today it say's I can't request again. Either they are way behind or they aren't giving out the info.
