There are several active and very passionate communities online including Fragrantica and Basenotes.....things can get incredibly nerdy when discussing perfume, believe it or not 😀
There's also a fragrance community here on lemmy but I think it's all but dead now...
This is something that that bothers me..... I joined lemmy.ml around 3 years ago as one of the pirate subs on reddit made a backup community there in case they were banned.
Fast forward to the api debacle, I started to use lemmy as a permanent alternative, and made 3 of my favourite art communities- abstract photography, collage and printmaking
It's always been in the back (and sometimes the front of my mind) whether to move them elsewhere, partly because people commenting on their 'blanket ban' of lemmy.ml, and the fact that I sometimes feel that I'm on one of the 'pariah' instances.
It's interesting reading the comments here, especially considering the art communities are laid back, without politics, and haven't had any issues (so far).....
