I saw this in a race last night my bf was racing in. It was some 475pp pub lobby.
At the time I was wondering how they were able to do it without showing a name. Nobody else was entering chat txt because the race was going on, so it's not like I could see the rest of the chat txt was missing above (like when you're in the lobby as opposed to the race). I don't think most people even noticed, because they were racing at the time.
I know my bf wasn't paying attention, I told him about it later. He never saw it because he just doesn't pay attention, especially not during the race. He almost never enters anything into chat. We don't have a mic, so I usually get out the keyboard, but he doesn't even bother. He just races. People talk to him, but he never answers! haha. Sometimes he makes comments to the television set, but no one hears him but me.

.
Anyway, the space bar explanation sounds right to me. Hitting the space bar enough times would certainly do the trick to hide the name of the person typing. The chat only allows a certain amount of txt to be displayed at a time, and there's no way to scroll back. So all you'd need to do is figure out how many characters it allows, and space just far enough so that what you're going to type would be at the end of that amount of characters.
Seems like a
lot of bother for a silly prank, of course. But this was Saturday night, so I guess some people were bored with time on their hands.
Of course even at the time, I knew it wasn't really Anonymous or whatever.
They kept saying silly things. It was obvious it was a prank, simply because they sounded ridiculous & confused. LOL. It started with stuff like
"PSN will be down soon" and
"We want to bring down Sony", "We want to ruin lives"...
But then when someone asked why... Then they said,
"We're not here to ruin lives." "We really don't want to bring down Sony". haha. After the initial comments it was like they just started babbling for the heck of it, making random meaningless comments. And then someone started typing "There's a hacker in the room!" And it was probably the person who was doing it.

Because they weren't getting much attention for it.
I wouldn't be surprised if the person doing it was 3 sheets to the wind at the time. heh.
Griefers... *sigh*
