ban accounts, how?

[systech]

Ok a question for you guys.

 

I heard from peoples there need to be used the table banlist, other guys says it needed the table ipblock, other peoples says it needs the table users_block, other peoples says it needs bg_user_banned and im very confused about.

 

Now, if i have account X to ban, his user_code is 123456 and i want to ban this account, how can i do? which table do i have to use?

 

I made some test but cant get it working, also the table peoples claim to use "bg_user_banned" does not exist in the database..

 

can someone make some "clean" ideas about?
