In my case I have a WP network site with about 100+ sites, users were going from site to site and were commenting as the last person that was previously commenting. It’s a mix of custom urls, subdomains, and subdirectorys, ie. http://www.example.com & images.example.com & http://www.example.com/images/ would be three different sites.
If you give me a heads up on how comments should be pulling the user information I can try to investigate further on my end.
I should say, we’ve been struggling with the “invalid nonce” for a while now when going from site to site, that’s why I’m suspicious of what’s going on.
