Posting about covid-19 on social networks

I recently replied to a post on the Nextdoor site and I received a notice when posting about covid-19, to use reference from the WHO and CDC with the link, and when using the covid-19 virus name in reference to the virus...... is this necessary ? This seems so off to me or am I overthinking it? It seems to controlled to me especially considering the CDC and WHO were a step behind in all of this. There are other trustworthy science and math based organizations and institutions publishing results and studies. —— I’m having a coronavirus annoyance moment
