After going through your post, I had to search "dplay" on ninjastic.space, and it turned out that you are. Most of the users I saw mentioning the casino were newbies, and they usually do it by mentioning other big casinos and then adding them to it.

Another thing I found about the site is that there is a link on freebitco.in that takes users directly to the site. I don`t know the relationship they have with them, but that reduces my suspicion towards them (although the newbie account shilling is not good for their image).
