tnaflix, empflix, shufuni never asnwer, so for now I'm just keeping all found links in a file for some future actions.
xvideos are somewhat reluctant but eventually delete your videos if you contact them enough times
the least offender is redtube, found only maybe like 3 or 5 of our videos there over the years (nothing compared to hunderds and thousands at other tubes), and they react promptly. but it is still worth it keeping an eye at it.
xhamster post our videos daily, but remove them daily too.
tube8 give you a producer account after you sent them several takedown requests - I have one and take care of our videos myself, no need to even send a letter.
pornhub never response to DMCAs, yet remove videos within 3-4 days.
hardsextube is a small fish compared to others, but it got to my bookmarks at some point and I'm keeping and eye at it ever since. IIRC the guy who runs it is even a member of this board.
