I'd be careful asking that, their are some warezer's that browse these forums and they'll try to fill your head with trash saying it should be ok to steal software.... but you have the right idea, of reporting it, but here is where I have reported sites to before Anti-Piracy
The problem you get into when trying to destroy a site that you think is illegal is that there will be many reprocussions. Think about the knowledge these people have to run an illegal site, then the things they can probably do......I wouldn't want to mess with that.
