ijgeoffrey, would you like users blocking admins to be a normal thing?
Would you like admins to have to deal with the possibility that users do not receive group news because some users happen to have blocked the admin who happens to have written the group news item in a group?
It may be a nice idea to be able to identify which group and which admin a group news item is coming from (instead of just being shown that there is some new "message by chess.com" of which there can be a lot). It probably would be nice only if it does not lead to users blocking admins because of group news.
If members feel they are being spammed via the group news, but they don't want to turn off alerts, then perhaps the V3 system could have News alert messages coming from the author of the post, rather than coming from ChessCom like they used to. That way, the user could block one particular admin (therefore not getting alerts of their news posts), but still get alert messages for some (likely the most important) group news posts.
