Anyway, would n't it be possible to delete any sockpuppet accounts, and ban anyone from creating them in future?
I'm for free speech and all, but fraud is still fraud, whether it be IRL or online. And even one complaint of a person pinching someone's online ID should be taken seriously by all.
Not to be picky, but aren't you already taking someone else's identity?

Yes I'm being pedantic about things, but where do you draw the line? I think if the person is defrauding you or hurting your reputation online (assuming you have a good one to begin with), then perhaps something should be done about it.
If anyone took the sock-puppet of your seriously, even after it's been explained, then you might have a case, or those people believing it are royally stupid.
