I was googling hechsherim and ended up on oheltorah.com. It seems to contain a forum of people posting ingredient lists for products and admins judging whether or not the given product was kosher, for example, this or this. My initial reflex would be to say that this is not consistent with any mainstream Orthodox approach to Kashrus.
Looking into the authorship of the website, it seems to be produced by the children of a R Yitzchak Abadi, who is a talmid of R Aaron Kotler. Wikipedia:
oheltorah.com - A kashrut and halachah website by Rabbi Abadi's sons, including a Q&A forum answered "according to the opinions of their father, Rabbi Yitzchak Abadi."
Am I missing something? Does anyone hold that you judge kashrut based on ingredient lists with no actual supervision of the making of the product?
