Are manufacturers having discussions removed from Audiogon if they turn negative?

I have mostly been taking part of this forum occasionally, and from a distance if you will.  I have to admit I don't really know the kind of things that can go on, disputes or disagreements that can occur.  I have occasionally done searches in this forum using the search function to only come upon a thread that has been removed, oddly enough.

I have seen some discussions, and taken part in some others that become somewhat of a debate on certain brands, and they have become critical in some instances.  Usually fans of the brand in question rush to the defence, and from what I've seen, a healthy discourse occurs, with back and forth and occasional posts removed.  I'm thinking of smaller internet direct manufacturers such as your Emotivas, Schiit Audio, Ascend Acoustics and the like.

What I'm wondering is, have such companies had negative discussions stopped or removed?  Has anyone been part of similar discussions in which moderators suddenly step in and either lock or completely remove a discussion?

I added my two cents about the Tekton thread yesterday, and the entire thread disappeared by the end of the day. The admins here probably don’t pull every negative thread, only when a particular product attracts an avalanche of well-deserved criticism.
A moderator posted in that thread yesterday that it was deleted by the OP, not the moderators. Whether the criticism of Tekton was well-deserved or not is a matter of some debate, hence the activity in that thread.
My impression is that the mods remove threads when they become hostile or no longer remain on topic. Often times, they give a warning before deleting the discussion
That's what I've observed here.
Interesting, thanks everyone.  The Tekton thread was what I’d noticed recently, but have occasionally seen other threads with similar actions.  I’d say that this forum is much better than what typically happens at say AVS or some of the other forums.
Yes, the AudioGon moderator said the thread was removed by the OP. I assume he has reached an agreement with Mr. Alexander. That thread exposed, Tekton has a good product and loyal followers, their customer service department, might need some attention. Hope the OP will finally get his speakers.
It was a weird thread.
Both the OP and Mr. Alexander never revealed all the details of the order, and why it went the way it did.
Anyhoo, I hope both parties have reached a mutually satisfactory agreement.
When a customer has to resort to going public on a forum like this to get some traction on his prepaid order,that is a pretty sad reflection of how the manufacturer values his customers and reflects directly on their service.
I hope this person gets his speakers,falls in love with them and puts this all in the rear view mirror.Truth be told,lots of people read that, and will think twice about supporting a business that gives the customer the business. This manufacturer really owes this person  a sincere apology  backed up by a goodwill offering of a 10% refund for being a PITA.
