You should be able to block people through the recently played list.

Title. I can't tell you the amount of times where after going through a game I just want to get the fuck out of there so I instantly click the Home or Play Again buttons and realize that I didn't block the person/people that made me have such a bad game. Then I have to proceed to the recently played button, pray that they have a short name, hope there's no things like capital I and lower case l, and then waste 10+ seconds to block someone who might not even be the right person. This just seems like such a trivial thing to have and I hope people agree with me for once.
