I don't think they can outright ban you but they can limit your bets to the point that you aren't making anything beyond recreational money. Take a few thousand into a sports book in Vegas and ask to make some big parleys. Most likely they will limit you in some way. They also will require you to sign up for a players club card which requires you to show an ID and give them all of your information. They made a copy of my drivers license when I made a $3k bet at the Hard Rock Hotel a couple years ago.
On the other hand- right now with the economy in the tank and Vegas being closed, perhaps next month they will be so desperate for big bettors that they will take any and all action without limits. IDK. A lot of that is decided by the sports book manager.
