When I google my name, there is a twitter account that is my @lastnamefirstname (farily unique name); it has some pretty racist/right wing garbage posted.

I went through twitters' official "impersonation" channel (even though it's not really impersonating me), but they declined to take action.

Is this a liability in my job hunt? Is there a tactful way to say "Hey, if you google me, Im not this guy on twitter"?

I created a twitter account to have on my resume to "supersede" the one I don't control in the hopes that hiring managers would give the benefit of the doubt, but is there any other action I can take?
