This is an e-mail I sent to Ken Murphy on April 15 and never got a reply. I sent a similar e-mail to Eric about a week or so before without a reply too. How much more should I do apologizing if I even do not agree I was banned on the real cause and not because of a personal grudge against me?

To the best of my knowledge, you were banned after you disregarded the warnings you received about your inappropriate behavior. I do not believe it was because anyone had a personal grudge against you. AFAIK, it was because Eric received a bunch of complaints from forum members who did not like your behavior.
