I mean; make it look less like it has all been written by one person under different names.
It is not a big issue, maybe other visitors do not see it, just to me it was clear.
If other people see it, they will not trust your site as much.
Maybe you can add some titles in one of the blog entries, or make one with just one link on the buttom.
Also the links are all going to your own pages, (and then sent to the casino) which also shows it was someone from the site itself to make the blog entry. Some people will be fooled with this, but others dont, and you will lose those forever. They will not come back very soon.
