I got semi-invisible Google Play 1-star rating Recently I saw 1-star rating on an app. It was invisible to me when I selected any language other than English(US) in my phone. And the comment was empty. 

 
Image of rating in Russian / in English (click images for larger variants)

What to do with that. This is a bug?

Thanks!

P.S: Can't view the profile of that "Google user".
Comment in Google Play store separate for different countries.

You can simply add to URL &amp;hl=en where en is two-letter language code defined in ISO 639-1

For example:


https://play.google.com/store/apps/details?id=com.adobe.reader&amp;hl=en
(English)
https://play.google.com/store/apps/details?id=com.adobe.reader&amp;hl=pl
(Polish)
https://play.google.com/store/apps/details?id=com.adobe.reader&amp;hl=it
(Italian)
https://play.google.com/store/apps/details?id=com.adobe.reader&amp;hl=fr
(French)
https://play.google.com/store/apps/details?id=com.adobe.reader&amp;hl=es
(Spanish)

What is a google user comment ?

If we go through what is written here, we get that after updating review profile by user, play store simply replaces old user name by new entry A Google User. This can also be because of some reasons like reviewer changed his name or deleted his account.
