Self voting is allowed by the system and people shouldn't judge. It's a very emotive subject and as you say it seems to me less powerful people have the issue. What happens when they have the power? Will they not do it? Hmmm?
It smacks of jealousy to me and that's the worst human trait.
Lighten up those who are whining about this issue, go do a decent post that contributes to the community and quit the negativity.
I came here for freedom and I'm happy to follow the guidelines of ethics and morals but no one is going to tell me what I can and can't do. I rarely upvote myself but have done for different reasons. It's my right!
If the system is changed to take away self voting that's ok to if its the consensus.
