VirusTotal does not detect anything - yet.
But what's really interesting, is that the supplied SteamKit2.dll is different from the official version.

official:
Version: 1.3.0.37474
Date: 2013-01-17 03:49
Size: 1.474.048 bytes

gibtux:
Version: 1.3.0.36844
Date: 2013-02-14 20:28
Size: 1.650.176 bytes

Especially the significantly bigger size of 172 kB for an supposedly earlier build number but with a later built date is what makes me very suspicious.
Also, I have not verified that the supplied source code is indeed what compiles to the supplied .exe. So using this program is very risky and not recommended in my opinion.

Just curious, how did you figure that out?
You can't trade them yet, a lot of offers are fake and supply and demand are unknown. So your guess is as good as anyone else's, isn't it?

Probably for the same reason you are not in the chat either...

Did you enter it into a fake outpost?

Since we haven't heard from him for a while, I guess the issue resolved itself.
A fake Outpost alone would not do anything, you would also need to fake the Steam login page.
I guess there are easier ways to phish than trying that.

I'd like them to put them in the search options, it'd be nice to be able to offer on one before it comes out

Find just one and click on it. Then use the magnifying glass below the icon in the pop over to search[www.tf2outpost.com].

How are we supposed to know when you don't provide any details?

You're testing the boundaries with misleading trades, troll trades (imho), threatening other users with the report system, insulting other users, reporting posts that aren't spam... and then expect strict punishment for a simple "lol" comment in those trades as well as more leeway for your own actions?

You just don't seem to get that YOU are the problem here, not everybody else, not even the ones that post "lol" in your trade!

And another remark I can't hold back now:
It's hilarious how someone calling himself "I put my shooter in your pooper" expects maturity from others all the while not being so mature himself, not the least by crying for mummy to help with "lol" comments in his trades instead of handling it himself like a true grown up.

It's just one of those sentences everybody copies without thinking too much about it. I think it is a selling technique supposed to persuade that it is more likely to get what you're after faster by adding that trade instead of another. My experience is, that is not the case. And I also highly doubt it gives you any real advantage over other trades without it.

The best of them are those that use it to also low-ball you. They advertise something at a fixed price, say "add me for a fast trade" and then when you're already in the trade window, you get this: "add a ref/rec". And the worst part is, I suppose it even works eventually.

A simple "add me" should be enough. Maybe not even that is be necessary, but I somehow feel it is with so many people SHOUTING DON'T ADD ME, even for fixed price trades - what I will never understand.

Skipped reading half way though.

You're offering only 40% of the lower bound price and even only 36% of the average on bptf. Assuming that price is not way off, the only one that should be reported is you for making a troll trade.

Deal with it or spare us (and the mods) your whining! As Xile said, you had it coming.

The real reason you don't like the comments would be that you fear the idiot that might sell to you is made aware he is about to make a very bad deal, and not that you are overwhelmed by spam, isn't it?
I have absolutely no mercy for you.

If you get thousands of reports about spamming daily, then why don't you finally do something about this issue?

Agreed, ban those that open troll trades and report every single comment they don't like.

The interesting question is whether you can trade them from F2P without upgrading to premium.
The wiki says that you can trade some misc items from F2P, so this could be one of those exceptions. But who knows...
