No, they are VIP's, you're not a VIP because you're just taking, you're not giving, you have zero value for the business so they limit you in order to lower the amount of noise you're creating.
To give you an example, if you would enter a store every day for 7 days and taking 30 beers in your basket to the cashier, but in the end just tell them that you'll want 1 beer and they should return the other 29, after those 7 days they would get sick of you and limit you to 1 beer can per basket.
This is what is happening here.
Sportsbook and casino businesses are here to make money, if you limit their method of making money, they will limit your method of making money, that's just the harsh truth.
What you need to do is the following:
#1. Stick to one and only one platform, we are all connected and share data between each other, if we smell arbitrage, you'll get in trouble. Go through KYC. If you've done all of that, now you're marked as trusted.
#2. Share the wealth, if you won 10k on sportsbook, go to their casino platform and lose 1k on slots, now you have a good Profit & Loss sheet with the casino (P&L).
#3. After losing 5k on slots ping customer support and ask them for a VIP manager to get back to you, ask for a 10% cashback bonus on that lost money, now you have the contact of the VIP manager + some bonus on your account. Make sure to spend all of that bonus on slots to pump up your P&L.
#4. Don't be predictable, only cheaters are predicable. Mix up your deposits and bets, keep an excel sheet to track all the different numbers, this is important, don't trust your brain to invent new numbers with every bet, you'll fail at it.
Now that you're trusted, not predictable, and have a good P&L - ask the VIP manager to increase the bets.
Ideally have an excel sheet for these things and track everything, because we surely do track what you're doing, and if the ADPU (average deposit per user) doesn't have a good ARPU (average revenue per user), we'll just limit you because you sound like trouble.
