If I see many people posting the same issue here well maybe it can convince us that there's something wrong with Roobet but since this claims doesn't have enough proof so I will find this claim shady.
Well, I can understand that if I won some bet, but turns out it is all void 
I couldn't be more irritated. Although unnecessary, his frustration is reasonable for him, so I won't call it shady. Not to mention his friend also has some "issues" with Roobet.The thing I want to say is if he insists Roobet has something to do with it, collecting more verifiable and provable proof is the thing he should do, instead of rattling unnecessarily. Otherwise, it all has no meaning.
