Warning
 

Was there any hack when it comes to warning/or warned a member?
Its like a modifications in which you can warned him/her til 3x something like that,and after that, a ban will be given.

Are you talking about Infractions? That is default vBulletin.

any other modification/hack aside from it?because i want members to see if they have a warning..

I don't know - you can do a search.

I think users can see which infractions they get on their profile page (member.php) - no? I must admit that I'm not real familiar with infractions because we don't do them on my site.

I can confirm that users see their infractions in their usercp, the member page, and in the thread they got the infraction and you can set it up to they will see it in all their post. "Infractions 1"
something like that, I don't remember exactly

My members get a PM as well which is usually what they notice first.

anyway i already found the solution of my problem:
