One of our users what threatened by Coinbase with account closure after he placed a bet on our site.
The implication is basically that Coinbase is now officially in the business of deciding what you can and can't do with your own money.

this is not new, but it is strange that they have warned that user because i have heard that they close down your account if you use the funds for gambling and also this is clearly mentioned in their rules when you sign up and click "I accept" without reading it

They've essentially lowered themselves to the level of the likes of VISA and Paypal.
Should you decide to spend your coins on dildos and should Coinbase tomorrow decide that dildos are something they disapprove of, you may face account closure.
since they are simply a service provider you don't have to use them. there are a lot of other good bitcoin wallets that people can use. coinbase is only good for purchasing easily and then withdraw to your desktop/cold wallet
