If you get autofilled to top...
Don't play a damage carry top. That's just stupid and all you will do is feed. Just play a tanky utility top laner that isn't dependent on gold to be relevant. Feeding 12 kills as Fiora to the Riven by 20 minutes doesn't help anyone. When you become that useless and feed that much no one can win. You just handed the game over to the Riven to solo carry with raw stats, exp and gold advantage. If you were a tanky top laner you could endure and actually have a meaningful contribution in teamfights.
