Influencers care more than anyone about their engagement and reach, and simple cross posting the same content on every multiple social networks increases neither. To each his own, but it's just not a useful strategy. On nostr they are up against the human algo, which detects BS pretty quickly. Cross posting on traditional social media hurts your reach and engagement within their algos, and in some cases can even jeopardize their ability to monetize their content on those platforms. This is not simply me not liking cross posted content. It is a strategy anyone serious about their content, audience, and reach should avoid.
