Rez: The amount of users have been increasing exponentially. We are seeing overload problem we have never seen before and we are going to be out of VIP bots very soon if this goes on. :) Still much work to do from here.
Potato: Totally agree about security. That is why we are still only 'tesing the wallet' and not actually enabling Bitcoin trade. Not only we have to make sure everything is secure, we also have to iron out all the basic trading errors that may lead to any wallet balance errors.
However, keeping secure when using Bitcoin is a big challenge, because it's an attractive target for hacking and for dumping stolen money. For example, dispenser.tf cannot allow a situation where someone buys 500 keys with a stolen credit card, and then sells them on dispenser.tf for bitcoin. I assume they're aware of this, and the ways you can prevent it (contact me if you want to know).
Actually, I would like to know your thought on this. Could that be posted here or you must tell me privately?
I'll message you thru Steam chat
I too am interested in what method you think will protect a third party vendor from selling stolen first party goods in an user-with-user trading system.
It's a method for detecting items that may have been carded. It's not useful for individual traders ATM, because it requires tools that aren't publicly available and are not user-friendly (e.g. you have to code them yourself, really), and you need some experience to understand what those tools are telling you and make a decision based on that.
This is information which is only currently useful for two groups: (1) people running trading sites like dispenser.tf, and (2) people who want to do something bad. So, sorry, but I prefer not to discuss it in public, because I think that would only give bad people some new ideas on how to avoid getting caught (not trying to imply you're a bad person, I'm sure you're not :)
It's nothing very exciting, anyway, just a way of analyzing some ordinary data that Steam makes available via well-known APIs, to extract a bit more information. It used to be quite effective for detecting carded items, but TBH, I don't even know how useful it is these days, because I rarely do those kind of trades now, and Valve seems to be much better at preventing carding than it used to be.
