P/S. For Forunejack i still don't see the own forum
FJ doesn't have their own forum but it has a thread on here which you can check out.
Looking at the websites own forum as a cursor for deciding if it's legit or not is a bad thing to do!
Since if the forum is controlled by the website itself it's extremely easy to manipulate and delete the threads or posts that might compromise the reputation of your website.
The best thing to do when you're checking if a website is legit or not is to find reviews on 3rd party websites, such as bitcointalk.org right here.
You'll find posts that aren't moderated by the websites own mods and posts from legit users and gamblers that diced or gambled over there.
