How to optimize a gambling or casino sites?

Hello friends,
I want your help. Please give me suggestions, how to optimize a gambling site or casino site. When i do posting in bookmarking site and articles sites they all reject my content as they consider as spam. Please give suggestion how to get ranking of keywords and increase traffic?
Thanks in advance.................

Upload some youtube videos related to gambling/poker/etc, this tends to do really good if you do some Youtube optimization on the videos + keywords

Only video optimization is ok?
any other thing which we have to do?
