Did I break a forum rule?

Hi Mod,
I responded to "New Member--- question-- How does CDS affect the good bacteria living in your microbiome?" with a link to Dr. Kalcker's Substack article on CDS and the Microbiome. I noticed it didn't take. Was posting a link bad form?

PS: In doing my due diligence, I came across an extensive list of ailments CDS could help. I can't for the life of me find it again. Do you know where the list is?

That icon is a piece of chain plus a green circle.
