The good news is they certainly seem to be able to hash sometimes, at some level.
They had a software issue so it was unstable but it's been resolved.
seems they are hashing with more than 2TH when they change from solo to Pool
so it should/can only get better
Why are there no payments coming in?
More difficulties? Another random pool change?
If this is what they meant by:
This is a very friendly advice; tomorrow the mining address and hashing statistics will be posted for everyone to verify.
They failed again. And if we can interpret "tomorrow" within 24 hours of this post, again.
