It refers to an occurrence in October when someone send a lot of bitcoins to incorrect public address: someone fucked up and lost ALOT of money . Casascius stated that he thinks it was done by Luke-Jr's Eligius mining pool: Re: someone fucked up and lost ALOT of money

The way I understand it, these transactions were nonstandard enough that normal miners and clients would already refuse to relay or process them (but will accept them in a mined block). And that the only way these got into a block was that he teamed up with Luke-Jr's Eligius mining pool which has been modified to explicitly allow these nonstandard transactions for a fee (or other negotiated arrangement).

Earlier from the same thread, Re: someone fucked up and lost ALOT of money:

Maybe this helps. It seems MtGox made a mistake somewhere.

MagicalTux: that's a problem, but not the worst problem we ever faced

MagicalTux: all the broken withdraws have been re-issued

MagicalTux: just spent one week of BTC-only income
