You need to contact the system administrators if you are concerned. However, in the introduction to NV uses are told what is acceptable use. If people are abusing others, or selling (promoting) repetitively their posts may be deleted.

If you express a view and give your reasons everyone will respect your views. (NOTE: the discussions on Britney Spears earlier this year got quite heated)
