dtw: has NO messages from staff3
fre: has NO messages from staff3
gam: has NO messages from staff3
h1a: has a message from staff3
nyh: has NO messages from staff3
big: has a message from staff3

     , `profile_id` VARCHAR(20)
     , `sender` VARCHAR(20)
     , `message_id` BIGINT (20)
     , `this_user` VARCHAR(20)
     );
