I have seen that now a few times and there are some Users have written " Lafu01 " instead of " Lafu " .
The first thing that was coming into my mined when i readed that is , that the Users that have voted with Lafu01 copied and pasted from other voters.
I guess thats the case for my name , because there is Username here on the Forum with the name Lafu01 .
Result of the " Search for members " : Sorry, no matches were found.
Some username are hard to write without looking at the profile for few times, sometimes that's why voters copy and paste from other users. But for "Lafu", I think even though they close their eyes they still seem to be able to write it, unless there is username change with combined. So if that's wrong, I don't think they know who they voted for.
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.
