I give everybody the opportunity to fail.

Nope, i'm very picky about adding people. Even if we played in the in party together through mutual friends, there is high probability I won't add them.

Accept then never talk to again lol I'm weird I know.

on consoles only family or close friends. I think I have 5 psn friends.

Since playing Uncharted 4 I've been getting a lot of them, which I accept but I don't join their parties since their skills level aren't great.

I keep their requests pending for years. That way I don't have to make a decision.

I barely get many friend requests, so I accept I almost always accept them.

On my Twitter (@MythologyGamer) I make custom backgrounds for people and generally I get a lot of invites from people who like my work, so I always sent a message when I get a friends request and then chat a bit :)

Depends on the platform. Sometimes I do, sometimes I don't.

I used to accept randoms years ago. Now, I just delete the friend request if I haven't contacted the guy on a game.
