I don't know what the person did. I was just stating that there are perfectly legitimate reasons to not vote for a player if you have more candidates that you support than spots available.
If you go back in time and look at past Hall of Fame ballots there have always been at least 10 future Hall of Famers on the ballot. Some of them took 50 more years to get inducted, but they were on the ballot. Even now, there are way more than 10 players on this ballot better than the bottom 20% of the players who have been inducted into the Hall of Fame. There were at least a dozen players on this ballot better than Billy Wagner and he got elected.
Please forgive me if I don't understand the subtleties between "a jerk move" and "a jerk". Those look like the exact same thing to me.
