Something is off with this trade

I traded for a lightning sunder here: post2957248.html#p2957248
As you can see in the image, I can't accept. The referenced profile is in kyrillic, but when I hover it it shows my name.
When opening it, it says the requested user does not exist?

Super weird that guy used cyrillic for both the item sold report and the user sold to. I'm guessing they have an auto-translate feature running in their browser.

I've fixed it back to English characters now, should work fine.

Thank you, I was able to mark the trade as trusted now.

Your explanation seems plausible, kudos on that
