Fortunejack is pretty popular and very legit site which has been working for more than 3 years as far as I can remember. Moreover your question is too diplomatic lol I didn't understand whether I should say yes or no. Lol they are definitely legit and not scam. If you still have experienced something like this feel free to open a thread in scam accusations to atleast aware other people about any such thing. But make sure you bring proper proofs of any such thing.
I do agree that Fortunejack is pretty popular because they offer a variety of games and casino live dealers. But talking of legit, I never had too big a withdraw I could approve them but whatever amounts I withdrew they always send it on time (first withdraw takes 24 hours though as they do some due verification and try to detect multi-accounts).
I understand you support Fortunejack but you need to understand what he is saying, he means that he might have multi-accounts but that's common in crypto industry but I do understand that some guys make multiple accounts for bonus farming.
