Venus is inspiring all sorts of memes with this video.
What happened to Berdych and Kokkinakis is exactly why I ask what happened to the ATP and WTA Media training?
Most hacks happened because of weak passwords or the very unfortunate action of clicking on an infected link, usually, a link sent unwittingly by a someone in the person's own list of contacts.
Media training can help (if not entirely prevent) these unfortunate incidents.
Also help players to protect themselves from online abuse and harassment, maybe even raise the issue with the social media companies about ways to help in the process (also, the ITF may want to stop making sponsorships with betting companies, but that's a whole entire conversation).
