No. The website would be a drama magnet for fake reports and no one would have the authority to challenge it. A mob based Blacklist is infinitely more amusing and open to personal interpretation and server guild bias.
Besides running the website would be costly and reminds me too much of Mythic io score tracker crap.
You’d be lucky to get half that info in any open written format. If the Pserver reddit ninja posts can’t even specify horde/alliance let alone which server it’s pretty bad.
Back in the day, our server had a circulating list, and a group of players ran a web DB (php scripts with MySQL) that was used to track ninja looters, lowbie gankers, scam/con artists, raid guild hoppers, and generally aweful people. It was an official community black list, and worked out quite well.
