The Play Store REQUIRES a fully activated real-name Google+ Account to rate apps and leave feedback, so I've been wholly unable to communicate with the dozens and dozens of apps that request feedback.
Sorry friends. Blame Google!
It's a trade off, and real name policies don't only exclude negative posters.
(To expand: I tested someone's js project on reddit just yesterday, offering my platform, multiple browsers, a decent writeup, images/screenshots etc. But my reddit account is fully anonymous. If my real name was required, s/he never would have gotten that free help)
Do the developers give you no alternate avenues for communication? No email contact or anything?
Lets say you wrote a cool android app, but there is a little bug in it that is triggered by a phone you don't own or weren't able to test, I have that phone. I go to contact you, which of the following reports do you trust more -
From: mhurron [at] saminds.com From: Google+ Roman Fox
Now be honest, even though this exact setup probably smells off. Given receiving a email from the above or from the above Google+ account, are you going to trust one or dismiss one simply on the name of the account?
I find this quite funny with you being the anonymous guy and me being out there in the open with my identity.
Maybe you should answer your own question?
