Unfairly banned

My username is MrPandora without a space, "That username is already in use. If you are MrPandora and you have forgotten your password, click here."

It says "Ban evasion" Rise with the fallen, what does that even mean?

I've already sold 2 eggs, a shiny heracross, and a shiny tentacool for a total of $140
How have I done anything wrong?

 

As discussed over Skype, I've told you what you need to do.
