Looking through the chat and trying to piece it together from Google Translate, I'm not seeing anything besides what is most likely insults relating to male genitalia. If this is an incorrect translation let us know, but right now I'm marking this as "Invalid" because it just sounds like normal trash talk. If it bothers you, you can mute the person to not see their text or hear what they say over the microphone.
 
OK I understand this might have something to do with a scam based on the linked cyclowiki article. I can't find the text that was in the screenshot in their chat log, can you type it again so I can do a Google Translate? Or is there someone reading this who knows the Cyrillic alphabet and can help us admins out? So far I'm still just getting this to be a general insult but I'd like to look into it further. Can you maybe run it through Google Translate to give us a rough idea of what is going on? I'll change this to "Investigating" for now until we can get an idea of what is going on.
 
OK so my original thought was correct, he's telling you to shut up and suck it. That sounds like general trash talk to me, and relatively tame at that. Unless this is racial or something I'm not understanding, I don't see an issue here. I'll see if any other admins have some insight. Also, http://steamcommunity.com/sharedfiles/filedetails/?id=575802203 and http://steamcommunity.com/sharedfiles/filedetails/?id=575802162 give an error, like they were deleted.

I don't think this is racial or a severe case of insults to gender, religion, or sexual orientation; it's just trash talk to get in your head and mess with you. I'm going to go ahead and put this back to "Invalid" and see if any other admins understand this better than I do.
