galleries vs vids vs HD vids clearly means limiting bandwidth is the key to prevent rippers, but the number of files downloaded.
However, this means that weighting has to be added to the files like
a pic = X
a vid = 10,000X
a HD vid = 100,000X
or just add member monitoring to know how much each member is downloading and have someone actually monitor it
Or the reverse of sorts, have bw capping and when a member caps, have a "monitor" alerted so they can investigate why etc etc to see if it's a new member going in and ripping stuff.
None of these ideas are practical in the real world, so, as you were
