I have thousands of spam users. I use K2 and I would want to delete them from "k2_users" and from "users". I want to delete the blocked ones. I have tried deleting K2_users from the admin, but it does not delete the user from "users".
Any ideas to delete from both tables(using SQL) the users that are blocked? I think that the field "block" of the table "users" is the key.
