OF has implemented a new form of protection for creators that adds your user ID number as a moving watermark on videos. This is that Wide Vine stuff that you can't decrypt or bypass unless you just screen record from your android device. This watermark thing fixes that and identifies who the video was sent to and makes it far easier for them to take action that way. BUT, I can safely say that Lurn doesn't implement even the level below that's protection as I can easily save her videos and they aren't watermarked. So IF she's made that sort of content and sold it but she isn't broadcasting it for sale on platform, she for sure knows who she's sold it to.
