Claiming banned name?

I can't find his ban reason, but there are some requirements for this:
To quote:

Keep in mind however this requires to be a 200$ donator as well.

 

Sadly not. You can however have a minor name change when you have donated at least 5$.

 

They both have different requirements.
Minor name changes require 5$ or more donated. The following name changes are considered minor:

1. Removal of numbers in a name (Example: Name1224 to Name)
2. Replacement of a number in a name (Example: N4m3 to Name)
3. Removal of characters such as underscores or hyphens (Example: User_Name to User Name or UserName)
4. Capitalization or de-capitalization of a name (Example: name to Name or Name to name)
5. Removal of special characters in rare cases where the user profile glitches
6. Removal of random letters that do not add to a username (Example: UserNameAsdf to UserName, NOT UserNameGaming to UserName)
7. Minor corrections of spelling

The rest can be considered a major name change.
Requirements for a major name change however are:

• Have donated a minimum of $200.
• Have a join date which dates to at least a year prior to their name change request (OR are a $300 donor, which are eligible for a name change after 6 months / $500 donor, which are eligible for a name change after 3 months).
• Have 2FA enabled at the time of their request and pass an IP check (To enable 2FA visit https://www.sythe.org/account/two-step and for a guide see: here).
• Have not previously changed their name via the major name change system.
• Must have not been banned or had a DNT for more than 2 weeks nor received a pardon within the last 3 months. Cannot have a TWC at time of request either.
• A second major name change can be approved if you have had your name for at least a year and you are a $500 donor.
