I bottet since pirox and i am Not the expert. I think wrobot is Till wotlk Safe, because wow Warden was at Vanilla and TBC even a toothless tiger. But, and i think thats the Point, the Server self, has running other Software which records IPs, maybe tracerouts your Connections and generates Reports for the gm staff. Than the GM has only To Look To your Accounts He got reported and thats all the Magic. At summary, the dont use Warden, they use other Software.
