In a word-yes. There are some that do.
Steinberg has never really had a clear policy regarding was was verboten on their main forum. To be fair, it’s not always so clear exactly when a thread has gotten out of hand, but they have vacillated between using a light hand and a heavy hand. Honestly, sometimes I think the mods who also work on the revisions and upgrades get tired of seeing the negativity and the insistence on new features which they know are either not forthcoming or not coming soon, however, reacting by bouncing polite users into The Lounge of Irrelevance has been a prime annoyance of long time forum members for a good while.
A thing to realize-it IS their forum. They can do what they like. Whether they SHOULD or not is a matter of opinion.
