What do you mean? You are not banned man. It was just a reminder for those misusing the feature which is now taken back anyway. Also, that line is removed from the updates thread. It was not personally for you but a warning for people. You are not banned from anything and getting payouts as usual.
I don't understand your question. The validity of this offer is 7 days and it can be claimed only once. However, you can watch the ads, claim the rewards from daily rewards system of game, and refer other people to get 1,000 coins per verified one.
Then why can not I pay? I just won the match and nothing was added for winning? What are the changes?
How is that possible? DM me on discord so we could troubleshoot the issue. Probably you submitted the shares.
