@cub80_appleby@mastodon.stickbear.me If you wish to not interact with this person at all, and not allow them to interact with you in any way, you should block them, which will automatically unfollow them of course. I'm not sure if you can block someone who you've already unfollowed, but I'd think so, especially since they've favourited your post. So navigate to the notification that told you of the favourite, and you should be able to block.

@adam@fedi.adamm.cc I already did that though!
