It really isn't looking good now. With the BTC return per T/h less than the maintenance the accounts aren't doing anything. According to the T&Cs if it remain like that for 21 days - it's been 14 already - then contracts are void. Gone. No refund, no nothing. I have 140 T/h with them, so this is a serious problem for me! An easy solution would be to reduce the fees (as genesis has done), but that doesn't seem to interested them.
Very worrying times. It really seems BTC mining isn't profitably with difficulty going up, the value going down and maintenance being the same.
