Well I understand your frustration, loosing that kind of money to a game and I think It's too much either, if you have not invested it into some permanent things like land, deeds, UL items). Doing something in this game, that gives you constant loss and still continue it until all is gone, is not MAs fault though, but your fault not being able to stop. Thats gambling and many people trashed their lives by gambling. Frustration, Depressions etc. could happen if you can't handle this kind of stuff, but then just quit.
But you can't go around and accuse others of fraud over and over again. It's not protected by your freedom of speech and a false accusation without prove. If someone is conducting fraudulent activity, it can only be proven by investigation, not by asking a forum if they think they do or not. The only thing you are doing here, is causing damages to MA and to us (yourself included if you continue playing -> more players, broader market, game staying alive -> PEDs save, especially now with deeds) by spreading your false accuses and dragging customers away.
I think you should either send an E-mail to the swedish authorities, asking them to investigate MA or file a charge if you feel something fishy is going on for sure. But stop posting this kinda stuff on a public forum. If I were MA or forum admin, I would have banned you for this thread, because it's just a crime of its own, false accusation and incitement of even more false accusation, which could severely damage any advertising attempt of MA, creating monetary damage, reputation damage, creating damage for myself and every other player in this game, etc.
People who play this game and are on this forum should be able to have enough cognitive ability to do simple chain of causation brainstorming, _before_ they do something.
