No point in making everything a blog. Also there is no point in posting to Robo in the forums since he's usually not in them.
Chat room bans can be done by three members in agreement that an individual is in need of a ban. So unless Robo specifically spoke to you and said it was him banning you then you are falsely accusing him. It's pretty rare to see Robo ban anyone.
Also running around making angry public posts while claiming you're innocent doesn't make you Look innocent.
If you feel you've been treated unfairly you should private message an admin and explain your side to them. But what you see and what another see may not be the same. They may agree with you, they may not.
