@illyBytes afaik best you can do is hide them, by long clicking on a story of theirs you can press "hide story", but sadly all that does is just hide the story in a sub section called hidden stories
@illyBytes you could ask them to exclude you from their story's recipients? i've had one individual ask me to stop sending them stories. so i did. and it's not annoying at all for the sender. it says i share to "All signal connections · 2 excluded".
