I put a ":)" face in chat every time I kill someone...

Only if you die while typing :)

Edit: Even then, you still need to throw the game, and do so multiple times in a short period

Can be considered bm but it's fine to do that as long as you don't excessively type it. Time to time in-game is fine as I do the "?" sometimes.

Definitely not. I wouldn't recommend doing it because it could tilt some people, but that's just my own opinion. You should be 100% fine though, no doubt about it

Pretty sure you won't be.

Only if you are playing Yasuo

Grey skies are gunna clear up, put on a happy face!

The trick is to put a space in between for every kill. :) : ) : )

Probably not. I might stop after 20 kills as by then it's just rubbing it in. :)

No
