So, OF is going down the drain because of all those incessantly increasing scams (OF actually approves of much of the time) and JFF is going down the drain because of their even more robust DRM protocol set (turned ON) by
default on the entire platform for all models!
At least OF gives models the possibility to turn DRM on or off, but each model's portal doesn't say so, and they can of course turn it on (if it's off) w/ no prior notice.
JFF allows certain types of activities (watersports, outdoors, etc.) that may be proscribed on OF, there are much fewer scams on there (and you can always at least see the number of videos, posting date and running time before joining), but you'll need some sort of updated and effective scraping method to download any video file on there.
Also... Most users who download do not download everything! They only download scenes they particularly like that they may want to watch more than once and actually wank to, scenes they want to be able to watch a certain segment of in a loop in one or more than one media player at once (all of which can't be done on the portal's player), scenes they may want on USB in order to watch on TV through a USB port.
Those portals with DRM want to force the paying viewer to always rely on Internet streaming and all of its inconveniences to watch anything, and DRM sometimes worsens those inconveniences (constant buffering, etc.). I can't even believe this has to be explained those who implement DRM. Adult studio websites understood that a long time ago, and most allow downloads of any and all scenes.
Some of those models want DRM to make sure their stuff doesn't leak and so not too many people view it, but most paying ($$$) subscribers obviously don't want it to leak; they only want to download for personal convenience, and no porn put online (w/ face) on such portals is
ever completely anonymous.
