Just keep reporting. It's all you can do, but they'll most likely eat a permaban.
Edit: Also since the vids are on youtube of them doing it, you can easily provide that as proof also.

They won't, & can't, take videos or pictures into account for several reasons. The best (& only sure way) is to report the person in game.
