What's the list is based on?
Who paid you the most?
I mean lol, you should at-least mention what's the whole rating is based on, have you tried those websites by yourself?
The fact that you are doing a review is nice, but I think that if you want people to rely on this information and to actually put their money into those sites, you should atleast provide them with some details about the authenticity of the sites.
The list is based on the global rank it doesn't seem that reliable because ebettle is one shady sportsbook. Long time ago there's a scam accusation about them here that wasn't solved it was only because he's winning a lot of money. Also if they found out you use other sportsbook that uses the same odds provider (ultraplay) they could limit or delete your account.
