Blocking on Socials

I think it would be awesome if the city had a way to block certain usernames from seeing your content on socials (Birdy/Instapic). Sometimes you just want to share things without everyone seeing them and this would make it easier to feel safe and enjoy the city without worrying about specific people. It would really help create a more comfortable and positive community. It also prevents harassment and stalkers from trying to contact you via socials.
