Curate, connect, and discover
Yeah, I've always found DNI's strange. I understand the logic behind it, but ultimately you're better off taking action yourself to keep out unwanted company. It takes less time to determine if you want to block somebody than to wait for them to go away, and it's a LOT more effective.
"xyz DNI" blocking people is YOUR job, sorry. You cannot ask the world to simply move around you, you have to take control of your online experience or you will be fucking miserable forever. Most people don't read your bio/pinned/carrd before touching the posts that cross their dash anyways.
Also maybe worry less about if someone who likes something you hate clicks on your tumblr post. I promise it is not that fucking serious.
Also-also if you have this DNI because your friends/moots said or implied you have to otherwise you're somehow Bad and/or will be punished by them if you don't, that's kind of fucked and maybe you need less controlling friends.
