boddyboy Am I correct that there is no such feature currently implemented on GG.deals and so there is no way to manage the list of blocked users, specifically?
I think they meant things like avatar or username - these should be inherited from your GG.deals account, and you already can change that at https://gg.deals/settings/
Managing list of blocked users may be unavailable for this type of account.
boddyboy Am I correct that the site-specific GG.deals profile also inherits the e-mail address from the GG.deals account and use it for notification when subscribed to a News article comment section?
That should be true. However, I personally never got any notification while using site-specific profile, so it may not work at all.
In general this feature (site-specific profiles) feels like abandoned by Disqus, that is why it is disabled by default. If you plan to actively use comments section, I recommend to use regular Disqus account.
