|Please explain in those three games why I should get reported, and banned..|
You obviously act in such a fashion that the majority of the player base as well as riot see unfit. You may not always act like that, but the point is, if you do that sometimes, it will build up and bite you in the ass.
Get a clue. Stop having occasional ban worthy games (this is completely in your hands and nobody else's). If you don't, you will be enjoying a cup of warm permaban soon. The choice is your buddy.
