PSA: Just because it looks bad, or your team doesn't want to surrender...
...Doesn't mean you ever get to go AFK, or to start feeding.
You joined the match, play to the end. It doesn't matter what trivial excuse you come up with. It doesn't matter if you're literally 5 unranked players against TSM. It doesn't matter if half the team's already AFK. If there's even one other player on your team who hasn't already given up, you keep playing. Unless you or your wife is literally going into labor right then and there, or it's a life or death situation, you keep playing.
You never get the right to screw over your teammates. Ever. It's in the terms, it's in the rules, it's in the fucking Summoner's Code, as little attention you give to it as you might:
>Seeking revenge on your own team by intentionally feeding and helping the opposing team does not promote fair play. Keep a cool head if you fall behind, don't give up and always do your best.
Straight from the website. I mean, even pre-30's manage to not go AFK. What's your excuse?
And, yes, sitting in base and spamming surrender votes does count as going AFK. Even if you're still technically connected and at the keyboard. Just because the automated system doesn't pick up on it doesn't mean it's allowed.
