A bad server that stops creativity

When I joined this server I thought I could rp as Harry. So I submitted him. Then I tried asking for ideas about my OC and some people suggested Pendragon so I tried to explain the two scenarios. Then my ideas got denied so I decided to rp as Harry and then they stopped me from continuing because they didn't like my writing skills. And I explained about my OC that I can make the oc have the Pendragon last name but not being related to the Arthurian legends. Then I tried suggesting for an animagus OC. Conclusion? If you want to be in a Harry potter server where you can be anything normal then don't join. Just search for another Harry potter server.
