I am writing a window program which will run from the system tray. which will ping my phpbb board site to fetch new users registration information. So with the result i can check whether the user is spam user or not.

if i feel it is a spam user then i will delete that entry from the users table.

before deleting the users table what are all the other table that i should delete.

so that there will not be any unlinked references which will then in due course of time gets numerous and waste of disk space.

so i want to know what i should do before deleting an user so that all his other activities should be cleaned off before i deleting a user.
