You may have seen it (or similar posts) already but this post has some recent comments from a site admin on the subject. This comment includes an email address that will allow you to open a support ticket and this one advises the requesting user to post in the community, tagging them in the process.
At the time of this post, those comments are just under a week old so it seems like a good starting point and a way to provide admins with all necessary information to move forward without too much additional back-and-forth in messages.
