Answer 1

You'll need to pass the ID of the User, not their name. You can obtain a users ID by right-clicking their portrait (If developer mode is turned on), and clicking "Copy User ID" at the bottom

How to enable Developer mode:

1. Open up the Discord app
2. Click on the settings cog in the bottom left corner
3. Go to Appearance -> allll the way at the bottom
4. Toggle "Developer Mode" on

Additionally you'll have to instantiate a discord object with the id (as an integer) before passing it to the unban function

user_id = int(id)
user = discord.Object(id=user_id)
await ctx.guild.unban(user)
