The reason why Rollbit was able to maintained a good reputation here because they're fast to resolved the issue if the accusation is legit.
The issues can always be there but the legit casino is the one who resolved it and allow players to withdraw the amount which Rollbit has done always so this is why they came under legit casino list.There are false accusations against most casino which Rollbit has also faced in past but they should be ignored like trolls.
