If you were scammed by someone scaring you into giving up your items through false reports I highly suggest you report the group you were shown, the profiles involved and if thats not enough for you, directly message Steam Support and let them know how everything happened.

They wont be able to give you your items back but letting them know will possibly prevent them from stealing from other users.
