This is a suspected multi: djulic & wolfgang007.
Game number: numerous (playing together)
My playing partner suspected this was one player because of the nature of the fortifications. These 2 players, djulic and wolfgang007, were able to pass ridiculous forts to each other - things you just wouldn't do unless you were sure you personally were playing the next turn (coz no-one can really trust a partner to show up).
It has given this guy djulic a ridiculous advantage in his games - hence he is already Captain after only a comparatively few number of games.
Look at the 'Feedback Left' by each of these players and you can see it is written by the same hand.
When he was challenged about it (he made a mistake and accidentally wrote while logged in as the other player, ha!) he said "Oh, I'm playing for my wife. She is wolfgang007 but I'm taking her turn"
This is complete BS and, as the feedback shows, this djulic and wolfgang007 are always the same person and this has given them an advantage over all of us who play fairly.
Book him Danno !
