Don't use the VPN as well. Because it was written in their terms of service before.
Create and use multi accounts on gambling sites are prohibited. VPN is mostly prohibited on gambling sites.
Some gambling sites alllow to use multi accounts but only if you don't use it to cheat redeem code, promotion, contests.
They have machines and tools to detect multiaccounts so don't try to cheat them.
Your advice is correct. Don't cheat, break ToS and cry later. Nobody can help.
Can you show where it is written that we cannot use VPN ? Usually some people use VPN regularly on their system. The have to disable the VPN every time they need to play on FreeBitco ?
I think only multi account should not be allowed. Don't know what's wrong using VPN
