What do you mean? Most of the ones advertised on the forum are licensed in Curaçao and I have played on several of them for some time without any problems.
The other points would make it a bad idea to try such a site
Curacao is not a regulatory jurisdiction that represents trust, nobody is chasing down the many Curacao registered gambling sites that have run fly by night operations (which there are many) over the years
They're currently trying to fix their image by saying they will be a better regulator, it's all smoke and mirrors though
