Taken from the ToS of Cloudbet:

5.1.9.3. Only one account per customer/IP/household is allowed. If you attempt and/or successfully open more than one account, all of your accounts may be blocked, suspended or closed and any bitcoin credited to your account frozen.

---

In reality, they didn't even have to transfer any funds to your account. This could simply be an attempt to find out the rest of your accounts through your own stupidity (though they could just as easily check for the same bitcoin/IP addresses or any other means) - Cloudbet has the authority to keep any winnings.

Why did you create multiple accounts in the first place?

5.1.9.3. Only one account per customer/IP/household is allowed. If you attempt and/or successfully open more than one account, all of your accounts may be blocked, suspended or closed and any bitcoin credited to your account frozen.

If there are multiple accounts to a single person or IP address, then they can be closed.

And sure, Cloudbet could have stated that they would return the funds, but it could all be a simple ruse. Given your current standing, you can't really be complaining given that you violated the terms. The word "frozen" does not necessarily mean that your winnings are confiscated, though depending on what you've done with the multiple accounts, I wouldn't say that it's not a likely outcome.

I know, because persons, who also made bets were my collegues. I do not say, that I am not guilty. I had to be aware and predict that this could happen. I understand i breached the rules. The thing is, that despite violate rules, cloudbet said that will pay out, but now ignores me.

Seriously, you need to post the thing to their ann thread. Let more ppl see and pm cb forum rep. Post here is not fully working

Still no answer from cloudbet since 22nd December! 

Thank you! I will try to send PM to Cloudbet!

I hope you get a favorable resolution.

Because, personally, I think they should stand by what they said.
Granted, he was in clear violation of Terms and should face whatever consequence may be, BUT,

they clearly set the conditions he must meet in order to resolve these. If he has done so, then they also, must uphold their end of the deal.  If they have to ban him from the site because of the violation, then fine, but those funds(if cleared),

should be released. I'd like to think that they are still in the process of investigating all funds associated with his account(s) and would release them once everything is cleared.

If this is the case then a simple statement/message letting him know shouldn't be too hard.

Glad have never played on the site or even made an account.I hate how these business centered sites are operated.I can make 10 accounts if I want to,if your site has a problem with it,better don't allow me to make 10 accounts on the first place.I wonder how making multiple accounts would matter ? I can bet on 10 different games with 10 different accounts,my wish.Why are people even playing there ?

Op,sorry for your loss.Move on.

Sent them PM, sent several e-mails, wrote at twitter and Sportsbookreview, still silnce from Cloudbet
