Nah, he just did it to provoke a reaction from us. Like he always does. And, of course, it worked. Anyhow, he’ll always be VCO3 (that’s a letter “o” not a zero, dammit. Not directed at you, jali, but I see the mistake all the time) to me.
I admit his name makes my eyes go out of focus, so I propose:
TLDRIDKJKALOLFTW
I don’t know if this is an actual suggestion, but I always read his new name in my head as “turducken”. Ya know, like the chicken with it’s head up the ass of a duck with it’s head up the ass of a turkey.
Figurative heads and asses, of course.
Now that I know the original name, it explains the posting habits of this name. How about Slice Me Dice Me Make My Day
VO5 is hairspray so VO3 was close enough that I always thought of hairspray, or maybe hairspray in the eyes.

On the charges of TLDRIDKJKLOLFTW being a troll, the prosecution rests its case.
Hey. Go after the keyboardist, not the keyboard.
This one looks like a winner to me.
VCO3.1
Is Troll already taken?

Somebody Needs A Timeout! …or “nap.”

Actually, I always thought the username VCO3 was his most redeeming quality as a poster. It reminded me that even though he is batshit insane when it comes to most matters of the world, you could actually have an intelligent conversation with him about music.
How about: “The dipshit formerly known as VCO3”
Every time I see the name I mentally pronounce it Triddly Dick"
So, its as good as any for me.
I don’t get how allowing a name change that almost everyone is aware of is providing either anonymity or a “new start” 
I’ve always thought “fucking idiot” had a nice ring to it.
