Maybe you didn't know, I'm just going to assume you were a bit naive to the unwritten rules that will set off just about every screaming red flag.
Let's start with what we do know in this thread. Going from account creation to withdrawal in a week or less is going to set off their alarms, this is not common behavior. Going up that much in a short amount of time with a deposit that is a tiny fraction of what you ran up is going to set off alarms. And to pile everything on top of this, the worst red flag here is asking for a 24K withdrawal in one shot. That's asking for an audit.
Now, I'm going to assume you got on a heater by betting on soft markets, hitting them live and just firing away. If so, that's going to get their alarms going, and then they start talking about syndicates, not being a rec-bettor and using advantaged play tools.
That still doesn't mean it's right that they put you through the wringer or confiscate any money but you have to know what kind of environment we are in. un-regulated stability has fallen off a cliff and Bovada, as of the last 6 Months or so have stepped up their audits and are shifting gears. It used to be they would suspend your account and then after an investigation, come back with hard limits but reinstatement but now they are closing accounts but still paying out for the most part but there's cases too, where they will keep the money.
I wouldn't panic now, just continue to give them everything they ask for an check with them, cordially and repeatedly.
