Also: Just look at the majority of the comments here, jonrick46. It's quite clear that these FReepers (zeestephen; Basket_of_Deplorables; minnesota_bound; kiryandil) are desperate to learn more about the link between blood clots and the Jab - not between blood clots and the "little known reasons" you mention.
Their frustration over articles like this one here - that report on a YOUTHFUL, ATHLETIC celebrity getting a blood clot in her arm YET NOT MENTIONING ANYTHING ABOUT HER VAXX STATUS - definitely overshadows any curiosity about "little known," "obscure," and "uncontroversial" causes of clots. Rather, that's what Wikipedia is for.
