I use `vipw' to place an asterisk (*) in the first character of their
password field.

  deadbeat:*$1$B0i0:1008:69::0:0:Slow Pay:/home/spay:/bin/csh
           ^
You could use vipw to change their login program to /usr/bin/false or
/nonexistent.

  deadbeat:$1$B0i0:1008:69::0:0:Slow Pay:/home/spay:/nonexistent
                                                    ^^^^^^^^^^^^
