Perhaps an effective technique against this is to make sure there's copyrighted music playing in your livestream. (Or does that get auto-killed by content watermarking?)
"Meanwhile, Tracy Jordan (Tracy Morgan) pushes Liz Lemon's (Tina Fey) buttons as usual by not showing up to rehearsals and leaving work to do something insane. However, Tracy's demeanor instantly changes when a camera crew starts to follow him around for his wife's new reality show. He starts to act responsible and respectful in front of the cameras, as not to ruin his chances of winning an Oscar. Liz has the idea to use Tracy's fake good behavior to get him to do things he blew off in the past, knowing that he can't refuse while taped. This works until Tracy finds a loophole. When Liz tries to get Tracy to do more things, he refuses and insults Liz to the melody of "Uptown Girl" by Billy Joel. Since the song is copyrighted, any footage containing that song can't be used. Therefore, Tracy's irresponsibility wouldn't be aired on the show."[0]

You committing a copyright violation isn't going to stop news organizations from doing something that is textbook fair use, except by getting your content pulled from the distribution platform for the violation before the news organizations sees it.
