Description:
So he just added me randomly and offered to buy my unusual. It felt a bit shady, cause I checked his backpack and he clearly didn't have what he said he was offering. After that he posted a link to website, I clicked it but lucky me had noscript going so it didn't do anything. Upon a bit of investigation it appears it's link to keylogger/malware that looks like just subdomain of image hosting website - http://www.reddit.com/r/tf2trade/comments/urlh4/q_new_scam_attempt/ .
I've been checking his friends activity and it appears that he's adding/deleting people, so I'd like at least warning on him farily quickly.

Should I report spreading viruses/malware to Valve in some way? Cause I find it even worse than just pure scamming of items.

Its a phishing link, and is an offence that can be marked for. Thanks for the report.
