Porn sites/networks that don't allow downloads

[BusterLoads]

Figured I'd try get some help on this but after learning that Brazzers removed their download option for videos and learning that Naughty America has no download option for their videos only after subbing, I'm trying to compile a list of all the sites/networks that don't allow members to download videos to avoid dropping subs to them.

So far I only know of three networks: Brazzers, Naughty America, and Reality Kings. If any of you know of any more, please share.
