From their Terms page:


In the following conditions, your account may be closed by us, and will be viewed and evaluated individually by case. We reserve the right to suspend your account without notice, which will remain suspended until complete investigation of the matter. You commit to completely comply with all of Adkinsbet 's inquiries into such activities. We may opt to upload or close your account if one of the following ap-plies:
If you have more than 1 registered account with Adkinsbet.
If the name registered on your Adkinsbet account does not match the name on the required statement from your address and or ID card. Of course, we take into consideration that all countries have different ways of express names.
If you attempt to use your customer account via a Proxy, VPN or similar service that masks or manipulates the identity of your actual location, or otherwise de-livers intentionally false or misleading details about your citizenship, place or residency, or other relevant personal data. If VPN is being used for betting or betting through a third party or on behalf of a third party using the website; or whether you are attempting to take undue advantage of the bets you have made. It is therefore critical for what purpose is using a Proxy or VPN. It is also possible that the user only uses this to optimize the connection. However, each user is responsible for the correct use of such connection, and it must comply with the conditions (i.e. do not use it to circumvent a jurisdiction where online gambling is prohibited).

The user has already indicated that he deliberately masked Russia and therefore used a VPN. That therefore falls under the manipulation of a location.
Simple conclusion, the terms have been violated.
Optimal use of a VPN connection means that you could use a VPN somewhere nearby for a more stable network.
This user has only done it to manipulate his location. The reason he gives is irrelevant why he wants to get around Russia.
He already admits he does not want his location to be showed as Russia, easy as that.
What I read from their story was that these users all tried to get a bonus and then run with the bonus money, and then create another account again for a new bonus.
Case closed.
