Answer 1

You can disable WM_PASTE

A quick test in a User Control derived from TextBox :

        protected override void WndProc(ref Message m)
        {
            switch (m.Msg)
            {
                case WM_PASTE:
                    {
                        Console.Beep(5000, 10);
                        return;
                    }
                    break;
            }
            base.WndProc(ref m);
        }


       public const int WM_PASTE = 0x0302;

Although it is possible, it is better not to do so because the user will not be able to operate it intuitively.
