How do I block a #?!
So what I mean is that i don't want to see posts that include a specific hashtag, for example #tunestr (I don't need music tips in my nostr feed atm, but my feed is full of it)

I was sure I've already done it in the past, but I don't see how atm?! Or am I mistaking?

I'm using amethyst

thanks in advance
