Only Famdom staff can give you an answer why was the wiki closed. Considering the topic and how quick it was, I can imagine some exotic reason such as posting classified information, but it's nothing more than a guess. The contacting form can be found here: Special:Contact.

About the rename - the reason was stated clearly: There is already a very similar username. Probably it's DBUG 000. If both of the accounts belong to you, you may try asking Fandom staff to allow you the rename.
