Access list when creating an account

I'm creating a login system, I need an access list in it. Who can I allow to log in and who can I refuse. My model:

[Display(Name = "Access List", Description = "Access or deny list. Ability to set name, e-mail address, telephone, IPv4 or IPv6")]
public class AccessList
{
    public int Id { get; set; }
    public string Name { get; set; } = string.Empty;
    public string? Description { get; set; }
    public DataType Type { get; set; }
    public AccessType Access { get; set; } = AccessType.Denied;
    public StatusType Status { get; set; } = StatusType.Active;

    public enum DataType
    {
        None,
        Name,       // User name
        Mail,       // Adress Mail
        Phone,      // Phone number
        Domain,     // Mail domain
        IPv4,       // Adres IP v4
        IPv6,       // Adres IP v6
    }

    public enum AccessType
    {
        Denied,     // Black list
        Access      // White list
    }

    public enum StatusType
    {
        Inactive,
        Active
    }
    
}

[Display(Name = "Access List", Description = "Access or deny list. Ability to set name, e-mail address, telephone, IPv4 or IPv6")]
public class AccessList
{
    public int Id { get; set; }
    public string Name { get; set; } = string.Empty;
    public string? Description { get; set; }
    public DataType Type { get; set; }
    public AccessType Access { get; set; } = AccessType.Denied;
    public StatusType Status { get; set; } = StatusType.Active;

    public enum DataType
    {
        None,
        Name,       // User name
        Mail,       // Adress Mail
        Phone,      // Phone number
        Domain,     // Mail domain
        IPv4,       // Adres IP v4
        IPv6,       // Adres IP v6
    }

    public enum AccessType
    {
        Denied,     // Black list
        Access      // White list
    }

    public enum StatusType
    {
        Inactive,
        Active
    }
    
}

If the data in the database is a regular string, there is no problem finding it. The problem starts when I want to do a regex. For example: we have a username, we can do e.g. fuck, fuuck or some variation of it. (I'm not strong in English). It would be nice to do it with regex, now the question is how to search for such data in the database? Also, won't the regex become very slow at some point? The plus is that we search short phrases (max 320 characters).

Your question is not clear, what are your trying to do with regex?

It doesn't have to be a database, I wonder if there is any other way than foreach and try every possibility.
