Yeah in your case I wouldn't worry about it since our stake doesn't make a dent compared to what's happening. My argument boils down to...
Can't all self vote, because the platform will be stale and nobody would stay. Then if we can't all self vote, why are we condoning self voters at all?
I am fairly certain I haven't self voted and I guess I see that people would do that if their position or whatever afforded them a reward for that? Idk. But I'm also pretty sure I wouldn't anyway. Kind of self serving and I don't know, not really my style.
