is he a spammer or what?
Well if we are talking about com_content, then you could modify the file:
administrator/components/com_comment/plugin/com_content/josc_com_content.class.php and near the end of the file you have 2 functions that are used in the module - getmostcommented and getothersquery .
There you should modify the SQL to not include the userid.
Module mod_comments not show comment of a specific user!
