Trying to trade with someone

So yesterday I added a guy who wanted to trade his knife for a rare background so i added him.
I got the background and wanted to send him a trade offer but it says he is on a trade ban even though on steam rep it does not show he has a trade ban.
My question was if this is a possible bug in the system or the steam service is slow with updating ?

None of his recent additions/removals have a public Valve Trade Ban... I think the account was soft-banned to get the owner to contact steam support.

yes i did why?
(I got scammed or something didn't I?)

well great just saw that this had happend before oh well i guess :\

this is the only profile I know off so i will have to dig deeper.

guess i will keep the background for myself

He was quite clearly making fun of you for calling backgrounds rare. They can be purchased on the market for pennies and there are hundreds of them on there. If it was rare it wouldn't cost you 4 cents.

Corrected that for you.

No, I was not making fun of anyone. These backgrounds can be very much rare, especially when brand new and bought up in entirety by one person, but as is often the case with trading cards and backgrounds/emoticons, rare does not mean valuable. I was asking if he bought that item because it's a variation of a known scam I've run into a few times, which we do apply tags for. If he answered yes I'd tell him to fill out a report.[/quote]

Oh that makes sense then. I had never heard of or even though of such a scam. But that does indeed seem to be the case here . http://steamcommunity.com/market/listings/753/317610-Page 23?filter=prophour This is the rare background in his inventory and it has been inflated up to and sold at $50

apparently I'm freaking terrible at getting this quote thing right...

you edit the tags, which you should not do. in above case, you accidentally removed the "] at the end of the opening quote tag, and replaced it with a single end bracked ( ] ), which then meant a " was missing....

Ah I see... Not sure if you can see deleted posts but if you can I messed up even worse the first time. it quoted it but turned the entire quote (and my text which got cut off for whatever reason) into one big hyper link directing us to the link I listed above.

that issue is where you put the cursor behind a linked text (url) and start typing. The newly typed text becomes then the custom text for the URL. It is simple to prevent: click the unlink button in the bar above the reply while your cursor is within that text

Button I mentioned:

The person I bought it from is not friends with the person I that wants the background or is this just so he won't be detected as scammer but I will have to wait untill tommorow because then the guy will be online again.

I was not aware of any scam at that time so I do not have any screenshots about the agreement on the trading
