those who account who get blocked it's because you received more rewards than you should have, so they block the accounts and once they removed all the extra rewards, they will unblock it

there is people saying that the tanki fund got boosted because there is players that bought the bundle on the tanki test server and it worked on the actual tanki fund, I wonder if it's true but it would explain the abnormal rise of the tanki fund out of the 1730 players if everyone bought the big bundle it would amount to 13.8M which is less than the actual tanki fund and i'm sure more than 60% of the tanki fund buyers only bought the 990tk pack
