I love the people who friend request you after game to continue to flame you.

dont accept the request then.. pretty simple bro

I'm just wondering why you would even accept their friend request in the first place...

My favourite is when they add you and immediately message: "So I don't queue at the same time as you."

U can block them you know

One time I was playing blind with friends and I picked Caitlyn top, the game ended up being remade, so I only got to lane for 3 minutes. The enemy toplaner added me after the game just to flame me for picking Cait.

I've heard about this happening for years, but I have yet to have it happen to me. I feel oddly left out... no one wants to be fake friends with me :/

I love when there's this thing called deny friend request which you can easily do :p

or you can accept and have send the conversation to riot

It's not that hard to look at people's summoner names when you mute them in game or report them in the post-game lobby. If they try to friend you, just right click their name on your Recently Played list and block them.
