Sonny: Someone from another forum posted:

"blockchain.info can't undo transactions. they can only let you attempt to double spend them and stop rebroadcasting the old transactions so they might disappear from the network before they get included in a block, but I'm not sure if this happens."

So, will blockchain indeed stop broadcasting these after a few days?

Too bad, it seems my info is wrong Sad

It depends on how you made the first transaction.
I heard that when it's from a blockchain.info wallet, then blockchain.info keeps broadcasting the tx
If it's from bitcoin-qt though, yeah you (he) can delete that transaction from your (his) wallet with pywallet

Also, bitcoin-qt can import keys. I don't know about blockchain.info but I think so

It is really bad that site will keep broadcasting the tx, even if the tx is with no fee and dust output Sad
