Declined 76561198036215934 ((PG) V3NOM)

So today, after someone added me for my craft #11 guillotine, he wanted to outright buy it. I thought "Yay, keys and stuff!" But he added only 3 reclaimed. I canceled the trade and he said he doesn't know what a craft number is. Obviously a failure attempt to scam. I even added the buyout in the notes.
So here's some pictures.
Used printscreen for this by the way, so that's why there's this exact tab in the in chat picture.

That doesn't look like scamming, that looks more like ignorance and lowbidding.

That's how they get off easily. They act newbie-ish and stupid to look innocent.

The evidence here does not show signs of a possible scam. Scammers generally don't operate like that- they will usually offer much more than something is worth rather than lowball. It seems the user here misunderstood what you said- at least that is what the evidence shows. However, it's always good to report something suspicious. Thank you for the report.
