Criteria used to rate a book.
1. Security - getting paid is by far most important.
2. Working with the forum. This is a player's thread and books are held responsible for their actions. Questions are asked of books concerning number of employees, time in business, experience, poster problems, etc. If a book is going to ignore a player's thread, they will be severely downgraded. Most books are very easy to work with.
The following cannot be quantified as to importance since being highly detrimental in one category may supersede other criteria used.
3. Poster review - poster review is much more important at bitcointalk than other forums, but other forums are also read. A high review from a new book will weigh less than the review of a book that's been in existence 2+ years.
4. Anonymous - one of the reasons that bitcoin books are used is to stay anonymous. There may be times where it is necessary to question players but it should be a minimum.
5. Margins - If players are going to have a chance to beat a book the margins have to be tight enough to give us that chance. If the margins are larger than -110 (1.91) that's a big blow to a book's rating.
6. Payout speed - If the average is longer than one hour, a book will be downgraded. One hour is sufficient due to possible grading errors. A large book is dealing with a significant amount of money along with a huge player base.
7. Markets - The more betting options, the better.
8. Traffic - time in business along with amount of players that a book has gives us a large sample size.
9. Currencies used - It's easier on the player if we are allowed to deposit and withdraw from alts.
Miscellaneous - Books accepting fiat currencies are omitted from the guide. Other forums are read to make sure the ratings here aren't significantly out of line with the average of other books.

There was an exception made for Sportsbet. Because of multiple poster requests and the fact that Sportsbet can keep balances in BTC, a rating was put up.
I think you should definitely post the criteria on main page because without digging this thread to find this post, it will be hard for other members to understand the criterias. I was at first amazed when I saw sportsbook in C class because it's one of the most trusted sportsbook right now.
I still think that it doesn't have a place where there are stake, bitsler, fj and similar casinos because sportsbet is on another level compared to them in sportsbook business.
Also, FortuneJack asks you to at least 2x wager your money in order to withdraw, so, idk why it isn't below C (but it's not high risk casino at the same time). I think this list and criterias need some modification and I'll may take my part in it if you don't mind.
+1
Exactly I was wondering the same thing just when I read the ranking, thanks for quoting it.
The criteria and classifications are tedious and no matter how many criteria you have, they are always subjective, but it is good to try to organize and promote this type of analysis, which is indicative and not definitive.
In particular, I do not know any of the D casinos in login mode but if there are several there that always get negative ratings, the others casino I use the most are in class C according to the criteria, but in my criteria they are class: "#·$5," "Ok" or Very good.
