Is there a rule that says we can use VPN? I tried to visit the site and the regional problem still appears like when they were first introduced on the forum, but this time I activated the VPN just to create an account. Wouldn't dare to take steps to deposit etc if there is a ban on users who use VPN. It's too risky for us unless you want to make sure by trying a minimum capital.
I just peaked through their terms and conditions a bit but couldn't found any information regarding the uses of VPNs. So those who are planning to use VPN should stop at once and wait until otherworld representative clears this confusion themselves. Regarding ban, if you are from a restricted region, your funds will surely be frozen or confiscated. They won't refund it, as it is written in their T&C.

I think people should know what they need to avoid. If they are in restricted regions then automatically they should not think about using VPN since this will just put them on risk to get their account frozen and their funds will be confiscated.
But if they are in allowed region I guess they should not worry about using VPN.
Still if they are doubting and want to make sure that there's no technical issues will came better not to use this and just gamble without using any tools which they afraid that can compromised them.
