Setting up a BV, privately held company, is a requirement for acquiring a Curacao license so they are either already licensed or in the process of getting licensed. Once you are a licensee you are not allowed to accept citizens from Curacao.
The BV is actually in Costa Rica rather than Curacao so there's no licencing issue. We actually moved the company there a while ago and wetsuit had discussed with me the possibility of adding new ToS at the time. The only reasons we discussed were to make the site look more professional and to keep the lawyers happy about not violating any CR laws.
It isn't having any effect on how the site is run. The only issues I deal with are multi-accounting and botting abuse.
