On the basis that you’ve only ever posted twice, and both posts have been asking (or demanding) why someone else has been banned, then I think that there may be more than an outside chance that you are the banned member.
If you are hoping that your membership will be reinstated then it may be better for you to to refer to yourself (eg “I”) rather than pretend to be someone else (eh “he” or “this person”). Pretending to be someone else may not help your case.
