REST API Get Subscriptions by User

Question

I'm hoping I just overlooked something in the documentation. Is there an API endpoint that will return all subscriptions a user has (e.g. following, application, thread, post, etc.) without iterating through every application/object on the site?

The In-Process Users API includes the capability to RunAs another user. You could leverage this either in a scheduled job that runs regularly to check old accounts as you mentioned, performing any lookups using the RunAs block; or in custom Rest Endpoints that accept UserId as an additional parameter and perform the RunAs block wrapping the in-process API.

These are different types of things, there is no one endpoint that will get you all of these things together. There are endpoints for each, however: 
 Applications: List Application Subscription REST Endpoint will return applications for current user (along with any other filters you provide) 
 Following: List Following REST Endpoint will return a list of followed users for the provided id 
 Content: List Content Subscription REST Endpoint similar to Applications

Looping back around here with another option: the Rest-Impersonate-User header can be used as the REST equivalent of RunAs.
