'Inappropriate username' refers to a name which a player has used in a lobby of a match or in a match itself. Please refer to my signature to see all reports ever filed against your account.
A report closed as guilty = Your account was suspended.
A report closed as innocent = Jurors or Staff have closed the report to state that your account is not guilty of that particular offense. Sometimes a judge may close a report as "innocent with exception" which currently still displays as "innocent". This means that the person may have broken a rule, but it wasn't serious enough to earn a suspension.
A report closed without judgement = A different report may have been closed as guilty or the report was open for too long without a verdict being declared, resulting with it being closed.
