Yeah a lot of the footage that guy posts up is just completely unnecessary, nothing incidents that most cyclists might react to with a brief shake of the head, if even that. As a cyclist you learn to pick your battles, assume the best in people and just get on with your day. This clown justs posts videos for attention, for the most part. Which is a shame, because occasionally he posts something genuinely shocking and dangerous but that gets overshadowed by the constant obnoxiousness.
On that note, I would disagree that no footage ever should be posted on social media, it's important that drivers see stuff from a cyclists perspective because too many drivers don't fucking think. Posting a video of an older woman who just happened to encroach on to a cycle lane though, that's just pure bullying and attention-seeking.
