It's completely OK for people to write unsigned recommendations, or to freely discuss music in as negative or positive a way as they like. There's a difference between something more official like a truly independent review, versus an enthusiastic debate or discussion.
Please note I'm not saying there's anything wrong with Joe LP's review of the Austere box set. I'm just trying to find a way to avoid this kind of thing in the future. If someone wants to discuss music in one of the assorted music sections of the forum, there would be no requirement to identify oneself, other than the use of a forum account, which can be somewhat anonymous.
What I'm considering is that in order to post in the "Independent Reviews" section specifically, there may be some kind of self-identification required. If a reviewer doesn't want to use a real name, they should at least post a link to a blog or other means of identifying who they are.
