Playing On A Friends Account

I am wondering if anyone has experience in playing on a friends account due to being limited on yours. I have recently been limited severely on an offshore site (Bovada) and I was hoping to pick the account back up on his account but I am worried I could get flagged.
I am wonder if using a VPN would work and if anyone has had experience in using these that you could recommend one?

IMO that is dangerous you could be flagged by everyone
