2 blocks in there with no transactions ...............
Edit:
For those 2 blocks (348622 and 348756) in both cases there was more than 70k of available transactions in default bitcoind (0.9.3)
@ Kano: Can you explain to a noob what this means & how it can happen? Thanks

In short
That means that Antpool is buggy
How can that happen
1. On purpose
2. Because it is buggy
3. 1 and 2

They refuse to relay transactions that is all
So does that mean that there is a possibility that they are keeping Tx fees for themselves?
