It is mysterious if Duelbits team haven't blocked your account completely despite knowing about your multiple accounts.
Maybe because I wasn't breaking any TOS? It could also possible that I was winning from the leaderboard and they don't want a winning customer. Who knows only DB can answer those questions because when I asked support they only provided me a generic response that excluding me was from the decision of their marketing dept.
That’s strange as, owning multiple accounts already bridges the TOS. Perhaps what they had on you isn’t concrete enough yet to bind you and so, they allow for some flexibility while they gather enough evidence against the accounts. That’s a case where you would almost get the chance to set somethings right and I don’t think it’s got much to do with the ladder board. They probation have got just the right number of gamblers on it.
