This is a hypothetical question. Imagine two estranged brothers hadn't seen each other in 20 years, but Bob kept a YouTube channel on behalf of some random organisation. Let's say John regularly watched this because he liked to see what his brother was up to even if he knew Bob would never return his calls. One day, Bob said something about their family that John knew to be completely false. Moreover, John found it offensive so left a public comment saying it was false.
Would Bob be able to successfully claim that John was cyberstalking him? If Bob then deleted his entire social media presence but John then found an obscure blog where Bob had spent years writing hateful things about John's family, would Bob be able to further claim that John was stalking him if the blog logged John's IP address? If not actual stalking, could Bob claim John was harassing him?
