[Zaz-Exploit]

so this is the code
in the part await unban(user, *, reason=None)

    async def unban(self, ctx, *, member=None):
        banned_users = await ctx.guild.bans()
        
        member_name, member_discriminator = member.split('#')
        for ban_entry in banned_users:
            user = ban_entry.user
            
            if (user.name, user.discriminator) == (member_name, member_discriminator):
                await unban(user, *, reason=None)
                embed=discord.Embed(title='', colour=discord.Colour.red())
                embed.add_field(name='Desbaneos', value=f'El usuario {user.mention} fue desbaneado\n**Razon**: {reason}\n\nStaff: **{ctx.author}**')
                await ctx.send(embed=embed)```

1. your submission doesn't appear to showcase a bug with discord.py but rather a problem with your code, in which case github issues aren't the appropriate place to ask for questions regarding your code, use the official discord server

2. follow the issue template for submitting issues
