What's your point? This is just the number of unconfirmed TXs on blockchain.info's node. My mempool is around 450 MB and ~60k unconfirmed transactions (at the time of writing this post). Someone turned up the spam today.

Why do you say 'someone' - how do you know?
From you as a mod I'd expect a bit more quality here ...
