Continuing the discussion from Discover Together: Public Release:
At least they have finally confirmed they are collection your data for their own needs. While we might have suspected this was the case, to my knowledge with regard to watch/rating habits, they have not written it down before for everyone to see.
BTW, can’t remember if I posted this already. However, if you have shared your libraries with friends then search your logs for ViewStateSync. You may see something like this …
... DEBUG - [Req#20f244/ViewStateSync] Got token for user 123456 (blahblahbah)
... DEBUG - [Req#20f244/ViewStateSync] Starting for user 123456
... DEBUG - [Req#20f244/ViewStateSync] Sending state
... DEBUG - [Req#20f244/ViewStateSync] All state sent
This is your server doing a sync against the plex cloud for user 123456. The blahblahbah is the users name so you can then take action and ask them to disable sync and if they won’t then you can remove their access from your server. Extreme, maybe but our data is important to us.
