There are a lot of bots still here so I wouldn’t be all that surprised.
Conversely I’m having the similar issue of blocking one community but then different communities with the same name and content still appear on my feed as if I never blocked them at all. Like playing whack-a-mole.
I’m a bit curious in this too. I don’t have an answer for you but totally anecdotal, I do notice I feel noticeably better even just halfway through a liquid IV which I’ve never noticed with any other sports drinks.
