There is a script that tries pushfit list but not sure if that is still working (edit: no pushfit has gone private I think or just dead), otherwise wait for the gdpr. Mine took about 3weeks but did come through, I think I got in just before the rush though as request the end of the first blackout week.
Yeah so I assume you mean the torrent of data. That is great but to be efficient you need to know what subs you post in otherwise you will be traveling a lot of data. Unless it is hosted and searchable somewhere.
