Declined Report: 76561198821972375 - ([None] No items)

@Menoly Report the user to Valve yet?

Lastly follow next set of instructions - BOTH of yours and the other account is private friends therefor we can not tell if you were even friends with this user and reporting the correct person or not via ID.
Issue is I can't confirm you were ever friends with this exact user by SteamID - all I see is a chat box with a name and profile image. Need to verify this and you can do that with a screenshot of your friend/user activity thru a web browser - when you take this and it shows you adding the user hover your mouse pointer over the users name so it shows the popup of the profile. Make sure you open this in a web browser before doing anything rather than steam client. Take the screenshot and make sure it's Full Screen, not edited or cropped in any way! Upload HERE…NOT imgur, NOT gyazo or any other 3rd party hosting site!

Please review this screenshot guide should you need assistance:

@Menoly You were clearly online and saw my request and thus far ignored any reply.
You have 24hours to follow up with what is needed to verify identity.

Declined for lack of evidence, verification of identity and lack of follow up as instructed.
Please do not submit reports here and abandon them like this.
