Eligius seems to have only said that a specific account isn't theirs.
So you should all ask a representative, has HashFast ever used/tested on mainnet [with customer equipment]? If they have, did it ever produce any amount of BTC?
If so, then there, you have an answer. If he doesn't release a statement one way or the other one can only speculate on what the facts might be with non-definitive conclusions.
Yes, the Eligius boss was kind enough to specifically repudiate the purported evidence showing HashFast mining with customer's hardware.
Since then, no other evidence of HashFast self-mining has been provided or even suggested to exist. Therefor, the charge should be withdrawn.
In a normal Scam Accusation thread (whether misfiled in Custom Hardware or not) the accuser provides their evidence and is expected to withdraw the accusation if the supposed evidence does not prove what is claimed.
I've already responded to the self-mining accusation:
We have internal test systems. A few of them, like the Baby Jet in our office that is part of the Eligius mining pool, are doing actual mining. This is to do a full, end to end, system test. None of these test systems will be shipped to our customers. We will not use customer systems for our own purposes, especially mining.
Best,
