Wanted to know if it is illegal to provide information on warez site For example : A site providing info on links to warez sites, links were to get warez, etc. i've seen a lot of google ads in warez sites so i dont think google banns warez sites.
Depends on exactly what you are talking about. Linking to actual downloads of copyright infringing material can be contributory infringement depending on where you live. Read the adsense TOS, you certainly can't run adsense on warez sites if you want to keep your account. There may be sites that do it, but they will get a lifetime ban when google catches them or someone reports them.
