Description
Ageratina shastensis is a woody perennial which bears unassuming fluffy white flowers about a centimeter wide. It is an uncommon plant which grows in the cracks of limestone cliffs of the Mount Shasta, part of the Cascade Range.[5]
Etymology
Ageratina is derived from Greek meaning 'un-aging', in reference to the flowers keeping their color for a long time. This name was used by Dioscorides for a number of different plants.[6]
gollark: Anyway, while this is at least better than passing all data through entirely unauditable serverside filters, I don't think it's very good.
gollark: Fascinating.
gollark: Four dots? Wow.
gollark: Even if you reverse-engineer where it gets the hashes from and how it operates, by the nature of the thing you couldn't work out what was being detected without already having samples of it in the first place.
gollark: Anyway, the generality of this solution and the fact that they'll probably keep the exact details private for "security"-through-obscurity reasons also means that, as I have written here (https://osmarks.net/osbill/) in a blog post tangentially mentioning it, someone could just feed it hashes for, say, anti-government memes and find out who is saving those.
