Following what we are talking about:
Yeah, when the voting started, I saw someone voting for "Lafu01" and I have forgotten it since a while but recently, I browsed submissions of new voters and saw "Lafu01" again. As far as I've checked, "Lafu01" has been voted for 3 times. 
So, posing a hint for that, maybe these members nominating "Lafu01" will edit their comments and new voters will finally stop copy pasting existing comments and also stop including errors.
Copy and paste is fine, but I think they still need to open the profile of the candidate they want to vote for to avoid typos. Like one of these candidates, The Skeptical Chymist - too difficult for me to write without copy and paste.
Yes, if in question, looking up those names (we have plenty platforms for this like BPIP, DdmdDdmr's Merit Dashboard, or even some sites from LoyceV like his Trust List Viewer), should be easy. At least, it would require voters to put in some effort.
