google plus has been known to terminate pseudonym accounts, so unless someone hacked into it, it seems to be genuine. a guy like vic is probably well connected, too, so it's quite plausible imho.
Not only have they been terminating accounts that don't use the owner's real name, they've started a "verified accounts" program, and the linked account has been verified.
The linked account also has 100k "followers" as well. I doubt a fake Vic account could amass that many considering there aren't that many on G+ yet. So the only other possibilities is that Vic is lying, or someone hacked into Vic's account, neither of which I think are true.
