Just for fun, What kind of player's behavior you don't like

Just for fun, after a long day.

So um, start with me. There are three types I don't really like:

1. auto-lock in ranked games, feed 2 times and then go afk. (happens often in promos)
2. type "?" when you make a mistake or fail to dive. (i usually dive as a jungler/support, or even top)
3. blame all day, from top to bottom lane. (no one is spear from his/her words, even though this guy plays very well).

How about your dislikes? Please share.
