Most of your post is about how it's not your fault and how it's unfair that things happened to you, therefore you feel the system is unjust. We get this quite a bit here, and usually the things that people say they were reported for are not the reason they were punished. Once they post their reform cards, we can explain to them why they were punished in hopes that they'll change their behavior.
In short, without proof that what you say is why you were reported or punished, we're not going to take your word for it that the system is unjust. Since you claim you deleted it already, I'm fairly positive you know what you truly did and you don't want it to be shown.
Spam bots are not a factor in punishes. For one thing, you cannot participate in Tribunal until level twenty, which is a significant amount of time to raise enough smurfs to be effective, secondly, Riot monitors people who spam verdicts/reports and those verdicts/reports are weighed less in the overall decision, as well as can revoke your rights to use the Tribunal and ban you from playing their game.
Your main point is that you got banned and you want an explanation. You threw your explaination away. If you were confused about what you did, you'd have posted it here so that we can explain it to you further. You did not. Therefore your main point is not supported because of your own actions.
