Paying all blocks are important, but is a small issue. These two unpaid blocks are just the one found out by user.

Another problem - not necessarily is cheating but need to be evaluated too.

Cex.io miners shared ghash.io pool with many other, unknown miners. With more non-cex miners are added to pool, the income of cex miners get into 'negative' value with the maintenance fee. Basically being robbed by fellows in the pool.

Non-cex miners in ghash.io got zero % fee.

After the fiasco yesterday, total ghash.io hash rate has dropped suddenly and income of cex.io miners has recovered but how long? Will someone add back the 10PHs and then income get back to negatives again? I think it will come back to 56Phs again.
