There is a very simple way to do this that is working well for me:

private bool updatingText;

public MyForm() {
    InitializeComponent();
    inputTextBox.TextChanged += inputTextBox_TextChanged;
}
private void inputTextBox_TextChanged(object sender, EventArgs e)
{
    if (updatingText)
    {
        return;
    }
    updatingText = true;
    try
    {
        var i = inputTextBox.SelectionStart;
        var text = inputTextBox.Text;
        inputTextBox.Rtf = "";
        inputTextBox.Text = text;
        inputTextBox.SelectionStart = i;
    }
    catch (Exception){}
    updatingText = false;
}

Since the Text property is inherently without formatting resetting the RTF text then setting the text property to the raw input removes any of the special items that may have been pasted in.
