After scamming someone for such a huge sum of money, there is no way SmallRabbit will leave the forum. If maybe some action was taken or at least threaten him, maybe he could have left the forum for good.
His real information will be needed to take legal action against him. Because as much as possible community members have taken action against him, you can check his profile has already been tagged. Now if a member can disclose the personal information of a @Small Rabbit, it is possible to take legal action against him using that information.
So let's wait and see what the result is.
