theres no illegal dupes, all dupes come from valve, but some are given to people after theyve been hijacked as a replacement and some are duped from hijacking, people make beleive there someone and get valve to give them a dupe or access to the account, theyre was for a small window of time russians duping hats but thats a while ago, and havent heard anything from anyone about new dupes coming out from that method

also it all depends if u care if its duped or not, if its one of my dream hats i wouldnt mind getting it for a bit less cuz its duped, but in other cases i might hesitate unless the deals killer.
