Please put a list of who we've blocked on our Friends page, along with an "Unblock" button next to each player. And a list of who has friended us, along with an "Add Back" button next to each player.
How about a list of people who have blocked us. I hate being surprised finding out someone I don't know has blocked me. Esp on the resource routes, standing there clicking the next stop on the route and it doesn't work, and I'm thinking it broke, then I look that person up and "hey, what is this?" thank the Giants it is easy to get around a block these day.
At least being blocked by unknowns won't be a surprise anymore. :)
