Aside from the fact that the old thread's mentioning of no phone number still holds true, he has zero reviews on his RM profile even through his profile is over two years old (his profile was created on 3/15/2020). For me, those are automatic must-not-hire red flags regardless of how a provider looks. Based on the old thread on this forum, looks like you are at your own risk if you want to take a plunge and hire him anyway.
