I didn't say you're wrong to do so. Everyone can have his own list of reasons, and noone is required to publish them.
Until now, I maxed out my 30 votes and made sure to have the lower ranking guys in, so they get to produce more often than the bots and inactives.
Everytime I needed a new free space, I had to consider the voting weight of the possible candidates. I'm glad to leave that behind me, whatever that means for my income. I hate to sell out my ideals.
