I'm still waiting for more generic explanation of what is acceptable and what is not. I'm sure it's not just about Erin.
So, in your opinion, where should the line be drawn? If Erin's stuff should be excluded, then certainly there shouldn't be any links to any product release stuff from manufacturers anywhere. Links to all advertisement funded sites need to be forbidden immediately. Of course no reports from Hifi shows, those are just advertisement. DIY projects might be allowed, but they usually showcase components from commercial entities. Anyone involved in the hifi business in any category should of course be silenced, so many conflicts of interest.
To me it seems the critique is of the usual "I'm not clearly stating why this is wrong, because I don't have any real arguments, but I don't like it"-category which has zero value to anybody.
This phenomenon we see here with some users is called "purity spiral". After "cleaning" the forum with reviews like the ones from Erin the community would further turn against themselves. So the line would in the end be a circle - around yourself.
