There is currently a few accounts ran by bots online (stewie2k, s1mple) that is only playing old streams and linking to a fake giveaway to get people to give up their account details. Watch out people!
u did nothing wrong as practice shows every time u will get attention for atleast 1 new people which can prevent them from scam+their friends.
btw i never saw post like this on hltv.
Only on reddit/dota2 but there was other streamers but everything was +- same
