I took my plat 5 rank the day before christmas, and the same day i got not only rainbanned, but also codebanned.
But hey don't worry only 7 days and i can claim again! (Joke) i got banned another time now, and will most likely get banned for the the whole month until the bonus i got from my levelup is gone...
Just to clarify I have wagered 500k for this month and is 900- for the week and still get codebanned.
Lesson: When you have 99.98% to your next level (Dont wager anymore) just claim all the codes, highrollers and such and then when you have 0 weekly wager you can level up. This way you wont miss out on any bonuses.
