For what is worth!
I am very satisfied with them, I am with Hash Flare since the middle of October of 2015, I did my first withdraw by the end of November, since than I have made weekly withdraws, all have been paid without any delay, I accumulate almost 1 Th/s.
My account was blocked during 30 days (for safety) because I did a direct payment with credit card. I recomend to read the fine print, they will block you if use credit card or change the recieving wallet.
Few times I used the support for questions related with pool allocation, they were very responsive and accurate!
I don´t see the point of spreading bad news about Hash Flare.
If you don´t like the company or don´t like the concept, just move on to something else.
Cheers
