So to clear up some things:
Yes, we do delete Wi-Fi Ratings on occasion including negative ratings, if we are messaged about it and we have reason to suspect the legitimacy of the rating. As much as it might seem like a bad idea to edit ratings, it's necessary to have the possibility of it open at times. Just like how there are bad people out there who scam others, there are also bad people out there who go out of their way to tarnish someone's name or just plain lie for whatever reasons they may have. We see it happen all the time. If someone comes to us about a negative rating, we'll consider reversing it depending on the user's history, any kind of evidence, and generally our vibe of whether there's something fishy going on.
I will be the first to point out that this is by no means a perfect or even great process, but it's what we've got and to be quite frank, there's not a ton to work with when it comes down to transactions like this. I have no doubt that there's probably been mistakes. In the case of the user in question regarding this thread's explosion, this might have been one of the cases where we have been wrong about the rating and wrongly reversed it given the additional reports/ratings we're getting now. I've sent out a couple PMs and am looking into this case in particular. I will also look into potentially providing some sort of limited compensation to those effected if we determine the cases are legitimate, but understand that we can't just go around handing out tens of thousands of bells around in these circumstances like candy, nor can we just make extra super rare collectibles out of thin air if a trade falls apart.
At the end of the day though, there's always going to be some inherent risk doing any kind of game code transaction or any transaction that involves outside services. We aren't Nintendo customer support. These things will happen with these transactions. We have been lucky enough on TBT for it to be a generally rare occurrence but that may change as our forum's reputation of being a marketplace spreads around, and some bad apples may come here to exploit that. We'll always do our best to keep things safe but the reality is what we can do is limited and mistakes can happen.
I overlooked that.
