I learned the hard way not to promote them and I would suggest no one else does either.
If you refer to this post: http://www.casinoaffiliateprograms.com/bb/doleplex-holdings.8368.html?
You will see that a CAP member was/is working for them and their payments. He goes by LawrenceW on this board.
The actual name of the casino is Real Vegas Online (it was changed from Vegas Frontier).
