I'd go for FMercury or some variation of that.
Probably about 1 - 1.5 million followers. But it depends how active he'd be. He wasn't much of a computer guy, and was very private, so maybe he wouldn't be a big user and thus wouldn't attract a lot of followers.
He'd have the usual P.A. (*in this case likely someone more media savvy than Freestone) doing the occasional update on stuff.
And his username probably would've been MrBadGuy.
(It would allow him to sell that warehouse of solo album cds)
He said he didn't read books, so baring in mind he didn't like sitting still reading, plus how he valued his privacy, I doubt he'd have time for social media - especially crap like Twitter.
^ Yeah but few celebrities and even wanna be celebrities actually handle THEIR OWN fb, Twitter accounts. It's done by PA's (personal assistants)
This screening process alone prevents em from saying anything ridiculous.
ATHLETES on the other hand, most likely handle their own TWITTER but not their own Facebook. (First hand experience with musicians/celebs, zero experience/witnessing with athletes.
I only know (probably cause I don't seek em out) of one rocker who handles his own Facebook. That's Steve Lukather.
Examples of crap you might see
"Miley Cyrus and I backstage at the VMA'S" # tbthisbitchintgewater
Of course he would.
Probably 1m+ followers
Freddie Mercury @FreddieMercury
He would post photos and videos of his cats. Some updates about shows, maybe a bit about what's happening.
