1 of 2 things IMO
i think this person has maybe 2 PS3's...? uses wireless broadband in the same house?
OR
he pays his mate, or for free, an says just stand there an i will keep shooting you.
as KoN mentioned in another topic
look at yulia backham, she had 155 kills in a row but when i looked at her stats today she improved to 300 kills in a row. i mean, cmon thats just sick...
there is NO WAY this is possible without cheating.
i notice aswell from other forums (i'll get later) that people are complaining saying that he cheats, i.e. dies a few times and complains an leaves immediately.
i'll pull up her stats from the konami website later!
