I don't know what you want to do with this. If you are thinking about targeting those countries with the use of VPN to gamble then I would not suggest that.
You might get yourself banned in the process and your funds locked away in that account. You don't want to lose money without even enjoying gambling first.
Gambling sites will definitely trace those who use VPNs and it's illegal for them because of many reasons. It ain't cheating but it could lead to that. But, there's not much trouble now because most popular online gambling sites do support many countries now and I highly doubt yours is part of those restricted ones.
Anyway, if it's for a project, then good luck.
