PSA: Announcing in /all that you can see enemies or have AFKs is assisting the enemy.

If you tell an enemy in all chat that you can see them in a bush, you just announced that you have vision there and they will then avoid that bush when ganking your lane next time.

If you announce that your team has an AFK, you are assisting the enemy team. They won't know where the 5th person is until you tell them. They could have thought they were farming the jungle, killing an objective beast, or waiting to ambush them. But telling them that your 5th is gone gives them free reign to pressure you and not worry when they kill 4 of you.

Don't do this shit.
