Club Admin Acting Unfairly – Need Help

Chess.com Staff rarely moderate private clubs, because clubs have less strict rules compared to the public areas areas of the site (mainly forum threads and in-game chat). This is why club rules (SA, Admin, Coordinator etc.) should be carefully chosen in a club; that being said, chess.com does sometimes step in. What you wrote in this thread, you should copy and paste (with screenshots etc.) to reporting, or otherwise contacting chess.com support:

Hello Chess.com team and community,
I'm writing to file a complaint regarding a possible case of admin abuse in one of the clubs I was a member of.
Despite being an active and respectful participant, I was removed from the club without any warning or explanation. I attempted to contact other admins, but received no response. Shortly after, I was removed again.
I believe the club admin may be misusing their powers, and this has negatively impacted my experience. I kindly ask that a human support agent or moderator review the situation and the actions taken by the admin involved.
All I want is to be part of a fair and respectful chess community.
Thank you for your time and understanding!
Best regards,

Below is a screenshot of the club activity log, which shows that I was removed and later banned by the user hoanganh04052012. I received no explanation, so I suspect this may involve misuse of admin power.
