When his account was limited, we also sent him this message:

"Hi,

Unfortunately, we do not allow arbitrage or any other forms of professional betting on our website. As mentioned before, we provide our betting services to recreational players only.
Therefore, a betting limit has been placed on your PowerBet account.
Now we understand your attitude on bitcointalk forum, you were trying to force us to accept your arbitrage betting by spreading out negative warnings and lies about us. We will not tolerate such a behavior.


PowerBet


P.S. As you already probably know, limiting/rejecting arbitrage players is a common procedure with all major sportsbooks."


Also, his registration details and IP was provided to Cloudbet (the sportsbook he used for arbitrage) so they can also take measures against his account should they consider it necessary:

"Hi,

We've identified a player doing arbitrage between our websites.
His email is m********0@hotmail.com
used IP's: ******
location: Greece
forum username: bestgr

We've closed his account and considered appropriate to inform you about this issue so you could take actions against him should you consider it.


Kind regards,
PowerBet"
