They do not run anything but BitcoinJ (evidenced by them blindly following invalid chains), so no proper consensus checking going on here at all. Connected to my nodes is a bad peer (doesn’t relay inventory but downloads everything) from 220.127.116.11, with the user agent /BitcoinJ:0.12SNAPHOT/Satoshi:0.2.0/ which is owned by blockchain.info. You can also submit an invalid transaction through their /pushtx interface and get a mixture of noise and BitcoinJ error messages out of it as well.
If even the people who have to their claim hundreds of thousands of wallets are relying on their security don’t bother running even a single node to sanity check against, who are we really going to expect people to in the future if the load goes 8x, 16x, 32x higher? Like CoinBase and others, these are the companies which are claimed will be the ones supporting the network with ludicrous sized blocks because they have a financial incentive to.
Well, they don't even do it now when it could be achieved with a $5 VPS.
