There are always gonna be people calling out scams. Sometimes they are right, sometimes they are not. IN the crypto world its always the same. A service comes up and this forum immediately tries to make some accusation.
Hashnet is a completely new company and service. They are in BETA Testing, not to mention that those company papers take time to process and i am not even talking abut the electronic documents. so it will take maybe more than month for hashnet to show up on british company search indexes.
Anyways, I am not saying that hashnet is the ONE, but I just want to say that everyone on this forum tends to have his/her biases and especially in the bitcoin world everyone has a huge ego.
Anyways, answering to the question you actually asked:
I was at the launch as well. Everything went smoothly for me as well. I had to contact support once regarding a withdraw, they responded within an hour and it was fixed.
I think it is a much better service compared to some mining companies out there now. Obviously there are better ones or more established ones like Hashnest.
But i do not like to put everything in one basket. So I am happy that hashnet.co came along.
