I don't know if camming is forbidden in Estonia.
But I've been told that in Russia, studios need to get a license and pay taxes to operate. Many studios don't have this license, so they bribe the police, which seems to be cheaper than pay the taxes. But even so, those studios that don't pay taxes nor bribe the police, they try to keep a low profile so the police don't find them online.
So, Russia or Estonia, she might have the same problem.
Honestly, I don't care anymore whether a girl is from Russia, Romania or Moon...
