Idk I don't see the point in just not doing anything and it's not about this "getting to me". I've learned my lesson and I certainly won't let something like this happen to me again but this is not just about me. I really don't like the idea of just giving up saying "well there's nothing that can be done". And yes someone can just make another account, but banning a scammer with a 7 year old account can only do good and if he comes back it will be much harder for him to scam someone with a completely blank account. Of course there will always be scammers but I think it's not a good mindset to just say fuck it. The concept of not banning a scammer because "he will just come back" seems just very weird to me.  

But still if this guy doesn't get banned, someone posted a list of known cheaters and I would recommend putting him there for people to know.
