Is there a thread where we can discuss
I discourage discussions about what goes on at other websites, for the simple reason that it opens us up to accusations of defamation. All I can recommend is to try and resolve any issue on the website itself, and if not, walk away.
from a publishers point of view, AW is not a fair website.
And so it shouldn't be. The publishing industry is full of pitfalls and predators for the unwary, and AW has a reputation for trying to warn writers about these. All publishers can be expected to do is demonstrate their professionalism in handling comments, questions, or criticisms.
In the meantime, Jo Zebedee has helpfully pointed out existing discussion on Austin Macauley Publishers, from which people can make up their own minds:
They're a vanity publisher and I'd advise avoiding them:
