Wikidot Community

You have to talk with the admins or the master-admin ( Owner) of this site, why they have banned you ( or your old user-name ?) from the site.
The Community can nothing do for in this case . The Owner ( or the admins with delegated rights ) is ( are ) responsible for the site and their membership

For NO REASON WHAT SO EVER!

Writing in capitals : this is called "Crying" and not a good behaviour in a discussion :( It is changing nothing and perhaps only showing your emotion.

this is my first time on wikidot, and I just got banned!

I think you have had a different user-name before and they know you from other text before?

If someone do not want to talk with you on a specific site and message you to the admins, than they can decide to stop your membership and / or to ban you.

I think you have not much chance to change this - perhaps only over the owner…

Well, you sorta were immature multiple times :/

Can't really help you, you'll have to talk to the TIBD admins about this.
