FWIW, Hashfast-cl has posted claiming that the only reason people are giving them negative trust is their scammy-looking self moderation. I responded, pointing out that while their self-moderation is concerning, my negative trust is because they've ripped me off. Sadly, they decided they didn't want people seeing that post either.
Using negative feedback to express dissatisfaction with a self-moderated thread is silly. If you don't like self-moderated threads, simply don't read or post in them.
My dissatisfaction is not due to the self-moderation, and I believe I am not alone in that.
However, sometimes certain behavior with self-moderation may be a reason to distrust a party. If self-moderation is used to remove substantiated criticism that may be a severe red-flag.
In my case my negative feed back is that HashFast accepted almost 98 BTC from me for mining hardware to be delivered at the end of October under contractual terms— and assurances in direct communication with staff as well as public comments— guaranteeing a full refund if Hashfast failed to deliver by December 31st, a very generous timeframe considering delays that long would almost certainly guarantee that the equipment would be at a loss at that point.
HashFast, as is well known now, failed their initial delivery targets in October, and later they failed their drop dead date on Dec 31st. As of today, March 5, there are many people still expecting and waiting for hardware with no idea when it will be delivered. HashFast tried unilaterally changing contract terms— demanding customers agree to additional delays and an additional NDA and an agreement to not disparage the company if they wanted to receive any hardware or a refund— even though the customers had an existing established contract in which Hashfast was in default.
I paid HashFast and have received nothing in return. No response to my communications asking them to comply with their agreement or otherwise settle the matter. Beyond a single email that they relieved my first certified letter I have no evidence that they've actually read a single word I've sent them. Other customers are already in the process of litigating against HashFast... Personally, I just want them to make good on the agreement as they expressed it and I understood it. I do not want to enter into an expensive and costly litigation which may ultimately leave hashfast out of business and unable to deliver the products to whatever few people are still purchasing with these substantial red flags at play.
To avoid any further confusion I've requested HashFast refund me in a publicly verifiable way:

Until then, I'd continue to caution anyone against purchasing any products hashfast is offering.
