I welcome big hitter / highly respected accounts to take a look at the case linked in your post, OP. The accuser has already had a case rejected by AskGamblers (regulatory body).
My understanding is AskGamblers rejected the claim without reviewing it due to their policy on not getting involved in TOS disputes.
I would also not ignore what anyone has to say for the sole reason that someone is a new user, or is using a new account. This mindset will give anyone a license to scam new users without consequence.
