I don't bet usually on Stake but today came back and had a good run and realised I had reached VIP- Bronze. Support give a good tutorial on benefits.I have some questions though-

1) The VIP rank that I achieve is lifetime or certain period?
2) Is rakeback allowed on sportsbook?
3) Also is there any VIP rank and wager chart to check the levels and their corresponding wager level to achieve that rank?
