Kickstarter campaigns do have to be submitted for approval, so theoretically there is a human reviewer. I'd assume step 1 would be "Google the names of the project founders".
Sure, but then you have the false positive problem that plagues the no-fly list or any other string based name matching system. It'd work for Judah Sher since that's a fairly uncommon name (his Kickstarter is in the top ten results). It wouldn't work for plenty of other people.
