Yes. I explained in one message that someone walked and stood at the enemy entrance on Hanamura defense to instantly die. Then he jumped off the cliff and finally walked to the enemy spawn to feed again during point B defend.
Another game I left the message that a support was AFK for the entire point A defend and then AFKd again for the first 2 fights of attack on A.
If you watch the replay it is just obvious throwing. Nothing done.
