This is something that the website does: If I’m logged in and view somebody’s profile, and that person follows me, I’ll see this:
<span class="follow-status">follows you</span>
However, I can’t find a way to accomplish this through the API (short of iterating over the cursor of the user’s following checking for my ID, which can take forever for users with tons of followings). Is there any convenient method that I’m missing, or is the site doing something that’s fundamentally undoable from the API?
