I just don't think it's fair to allow positive discussion of specific moderator actions and forbid negative talk. I will not weigh in on this particular moderator action, to prevent myself from being summarily suspended. I will say that there is, let's say, a diversity of opinion on the matter of which you speak.
If we're going to ban all talk of specific moderator actions, let's do that, and include the OP. If you really want to tell them what a great job they did, send a PM.
To allow your positive discussion of specific moderator action is unfair and presents an incomplete and deceptive account of community opinion on an issue.
